Abstract:
Three new lead(II) complexes containing the 1,10-phenanthroline ligand, [Pb(phen) 2 (3,5-DNB) 2 ] ( 1 ), [Pb(phen) 2 (3,5-DNB)(NO 3 )] 2 ·H 2 O ( 2 ), and [Pb(phen)(HCOO)(NO 3 )(H 2 O)] n ( 3 ) (phen = 1,10-phenanthroline, 3,5-DNB = 3,5-dinitrobenzoate anion) have been synthesized and characterized by elemental analyses, Fourier transform infrared spectroscopy (FTIR), thermogravimetric analyses (TGA), and single-crystal X-ray diffraction. The complexes 1 and 2 are monomeric species, whereas complex 3 is a one-dimensional polymer. In the three complexes, the ligand phen creates a number of π···π stacking interactions and hydrogen bonds, which play an important role in extending complexes 1 – 3 to supramolecular architectures. The Pb(II) ion of complexes 1 and 2 shows hemidirected geometry with noncovalent Pb···O/C tetrel bonds formed which further stabilize the supramolecular structures.
