The bimetallics [PhBi(Ox)2(NaX)n] (Ox- = quinolin-8-olate: X = Cl, Br or I), containing variable amounts of sodium halides, have been prepared by reaction of PhBiX2 with Na(Ox) (mole ratio 1:2) or of Ph2BiX with Na(Ox) (mole ratio 1:1) in ethanol. A similar preparation has given [PhBi(MeOx)2(NaI)n] (MeOx- = 2-methylquinolin-8-olate). The bimetallics have been characterized by X-ray powder photography, f.a.b. mass spectrometry and 1H n.m.r. and electronic spectroscopy. Sodium halide-free PhBi(Ox)2 was obtained from the reaction of Ph2BiCl with Na(Ox) in the presence of 15-crown-5, or from treatment of PhBiI2 or Ph2BiI with NBu4(Ox). Reaction of equimolar amounts of PhBiI2 and Na(Ox) gives Bi(Ox)2I. which can also be obtained from BiI3 and Na(Ox) in a 1:1 or 1:2 stoichiometry. Treatment of PhBiI2 with M(Ox) (M = Na or K) in a 1:3 mole ratio yields [MPhBi(Ox)3] bimetallics, which appear to contain both chelating and unidentate Ox ligands from their electronic spectra.

The complexes Ph3Bi(MeOx)X (MeOx = 2-methyl-8-quinolinolato; X = Cl, Br), PhBi(MeOx)2 and PhBiOx2 (Ox = 8-quinolinolato) have been prepared and characterized by electronic, IR and 1H NMR spectra.The crystal structure of Ph3Bi(MeOx)Cl was determined by single-crystal X-ray diffraction from diffractometer data.Crystal data: C28H23NOClBi, monoclinic, space group P21/n, a 17.05(1), b 13.89(1), c 10.51(1) Angstroem, β 97.30(3) deg, V 2468 Angstroem3, Z = 4, Dcalcd 1.70 g cm-3; R = 0.078, 3048 observed reflections.The complex is monomeric, and the molecules are well separated, with the metal atom in a distorted octahedral coordination environment.The metal atom makes with the bidentate ligand a Bi-O bond of 2.19(2) Angstroem and a relatively weak Bi-N bond of 2.71(2) Angstroem.
