    Tetrachlorido(1,10-phenanthroline-κ2N,N′)platinum(IV) monohydrate (2012)
    International Union of Crystallography (IUC)

    Publication Date: 2012-04-03
    Description: In the title complex, [PtCl4(C12H8N2)]·H2O, the Pt4+ ion is six-coordinated in a distorted octahedral environment by two N atoms of a 1,10-phenanthroline ligand and by four Cl atoms. As a result of the different trans effects of the N and Cl atoms, the Pt—Cl bonds trans to the N atom are slightly shorter than those trans to the Cl atom. The compound displays intermolecular π–π interactions between the six-membered rings, with a centroid–centroid distance of 3.834 Å. There are also weak intramolecular C—H...Cl hydrogen bonds. According to the IR spectrum, solvent water was present in the crystal, but owing to the high thermal motion of the uncoordinated O atom, the H atoms could not be detected.

    Publication Date: 2012-04-03
    Description: The asymmetric unit of the title compound, [PtCl4(C12H8N2)]·0.5CH3CN, contains two crystallographically independent PtIV complexes with very similar geometry and one solvent molecule. In the complexes, each PtIV ion is six-coordinated in a distorted octahedral environment by two N atoms of the 1,10-phenanthroline ligand and four Cl atoms. Because of the different trans effects of the N and Cl atoms, the Pt—Cl bonds trans to the N atom are slightly shorter than those trans to the Cl atom. The compound displays numerous intermolecular π–π interactions between six-membered rings, with a shortest centroid-to-centroid distance of 3.654 Å. There are also weak intra- and intermolecular C—H...Cl hydrogen bonds.

    [(2,3,5,6-η)-Bicyclo[2.2.1]hepta-2,5-diene]dibromidopalladium(II) (2011)
    International Union of Crystallography (IUC)
    Details
    Publication Date: 2011-10-20
    Description: In the title complex, [PdBr2(C7H8)], the PdII ion lies in a distorted square-planar environment defined by the two Br atoms and the mid-points of the two π-coordinated double bonds of bicyclo[2.2.1]hepta-2,5-diene. The complex is disposed about a crystallographic mirror plane parallel to the ac plane passing through the Pd, Br atoms and the centre of the diene ligand.

    Redetermination of (2,2′-bipyridine-κ2N,N′)dichloridopalladium(II) dichloromethane solvate (2016)
    International Union of Crystallography (IUC)
    Details
    Publication Date: 2016-12-20
    Description: In the title compound, [PdCl2(C10H8N2)]·CH2Cl2, the Pd2+ ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the 2,2′-bipyridine (bipy) ligand and two chloride ions. The compound displays intramolecular C—H...Cl hydrogen bonds and pairs of complex molecules are connected by intermolecular C—H...Cl hydrogen bonds. Intermolecular π–π interactions are present between the pyridine rings of the ligand, the shortest centroid–centroid distance being 4.096 (3) Å. As a result of the electronic nature of the chelate ring, it is possible to create π–π interactions to its symmetry-related counterpart [3.720 (2) Å] and also with a pyridine ring [3.570 (3) Å] of the bipy unit. The present structure is a redetermination of a previous structure [Vicente et al. (1997). Private communication (refcode PYCXMN02). CCDC, Cambridge, England]. In the new structure refinement all H atoms were located in a difference Fourier synthesis. Their coordinates were refined freely, together with isotropic displacement parameters.

    catena-Poly[hemi(hexane-1,6-diammonium) [[aquadibromidomanganese(II)]-μ-pyridine-2-carboxylato]] (2016)
    International Union of Crystallography (IUC)
    Details
    Publication Date: 2016-12-20
    Description: The asymmetric unit of the title compound, {(C6H18N2)0.5[MnBr2(C6H4NO2)(H2O)]}n, contains the repeat unit of the complex anion and one-half of a hexane-1,6-diammonium cation that is located on a twofold rotation axis. In the anionic polymer, the Mn2+ ions are bridged by the pyridinecarboxylate (pic) anion ligand, forming a chain structure along the c axis. The Mn2+ ion is six-coordinated in a distorted octahedral environment by one N atom of the pyridine ring, two O atoms of the two carboxylate groups, one O atom of the water molecule and two Br atoms. The compound displays intermolecular N—H...O, N—H...Br, O—H...Br and O—H...O hydrogen bonding. There may also be intermolecular π–π interactions between adjacent pyridine rings, with a centroid–centroid distance of 3.992 (4) Å.

    Description: The asymmetric unit of the title compound, [PtCl2(C6H4NO2)2]·CH3CN, contains a neutral PtIV complex and an acetonitrile solvent molecule. In the complex, the Pt4+ atom is six-coordinated in a distorted octahedral environment by two N atoms and two O atoms from two pyridinecarboxylate (pic) ligands and two Cl atoms. The Cl atoms are cis with respect to each other. The compound displays inter- and intramolecular C—H...O and C—H...Cl hydrogen bonding.

    Details
    Publication Date: 2012-04-03
    Description: In the title complex, [PtCl2(C10H8N2)2]Cl2·H2O, the Pt4+ ion is six-coordinated in a distorted octahedral environment by four N atoms from the two 2,2′-bipyridine ligands and two Cl atoms. As a result of the different trans influences of the N and Cl atoms, the Pt—N bonds trans to the Cl atom are slightly longer than those trans to the N atom. The compound displays intermolecular hydrogen bonding between the water molecule and the Cl anions. There are intermolecular π–π interactions between adjacent pyridine rings, with a centroid–centroid distance of 3.962 Å.
