    Notes: The transition metal-gallium complexes [Ga(MLn)3] [where MLn=Fe(CO)2(η-C5H5), Mo(CO)3(η-C5H5), Co(CO)3(PPh3), and Mn(CO)5] have been synthesised by salt elimination between GaCl3 and MI(MLn) (MI=Na/K). The iron complex [Ga{Fe(CO)2(η-C5H5)}3] (1) has been characterised by X-ray crystallography and shown to contain a planar, three-coordinate gallium centre bound to three Fe(CO)2(η-C5H5) fragments by unsupported Ga-Fe bonds [av. 2.444(1) Å]. A partial structure determination of [Ga{Mo(CO)3(η-C5H5)}3] (5) is consistent with a trigonal-planar GaMo3 core. Brief mention is also made of two chloro complexes [GaCl(MLn)2] [MLn=Fe(CO)2(η-C5-H5) and Co(CO)3(PPh3)].

    Notes: The structure of the dimethylzinc adduct with the bidentate amine 1,3-bis(4-pyridyl)propane, [Me2Zn(C5H4N)CH2CH2CH2(C5H4N)]n, 1, has been determined by X-ray diffraction analysis. Crystals of 1 are monoclinic, space group P21/m, with two molecules within a unit cell of dimensions a=5.364(3) Å, b=12.839(3) Å, c=10.618(3) Å and β=92.76(3)°. The structure is polymeric, being composed of [Me2Zn(C5H4N)CH2CH2CH2(C5H4N)] units with the nitrogens within a specific 1,3-bis(4-pyridyl)propane ligand bonding to adjacent zinc centres. The zinc atom is four-co-ordinate, bonding to two carbon and two nitrogen atoms, with the C - Zn - C angle of 145.5(2)° intermediate between that of a linear and tetrahedral bond arrangement. As far as we know, this is the first example of a polymeric alkyl zinc/cadmium amine adduct to have been structurally characterised. © 1997 John Wiley & Sons, Ltd.
