(NMe4)2CuBrnC14-n and (NEt4)nCuBrnCl44-n (n = 1, 2, 3) have been prepared and characterized by X-ray powder diffraction and far-infrared spectroscopy. The tetramethylammonium compounds are isomorphous with each other and with the corresponding compounds where n = 0, 4. The tetraethylammonium compounds constitute another isomorphous series. All the compounds apparently contain discrete CuBrnCI4-n2- anions, with flattened tetrahedral configurations.

Monomeric two-coordinate gold(I) complexes, [Au(P(mes)3)X] (P(mes)3 = tris(2,4,6-trimethylphenyl)phosphine, X = Cl, Br and I), have been prepared and characterized by single-crystal X-ray structure determinations, far-infrared spectroscopy and solution and solid-state CPMAS 31 P n.m.r. spectroscopy. X-Ray structure determinations show that crystals obtained from solutions of [NBu4] [AuX2] and P(mes)3 in acetonitrile for X = Cl, Br and I and in dimethylformamide (dmf) for X = Br and I form an isomorphous series of complexes, crystallizing in space group P21/c with a ª 8, b ª 22, c ª 13 Å, b ª 98˚ (a form). Crystallization of the chloride from dimethylformamide yields the solvated complex [Au(P(mes)3)X]·(dmf) in space group P2/a with a 15.224(2), b 10.070(1), c 18.210(4) Å, b 100.42(2)˚. Electrochemical synthesis of the complexes for X = Cl and Br yield two new crystalline phases; the chloride in space group P21/c with a 10.249(2), b 8.189(2), c 31.844(3) Å, b 91.68(1)˚ (b form) and the bromide in space group Pbca with a 19.208(4), b 15.586(3), c 16.962(4) Å ( g form). The Au–P bond lengths increase in the order Cl < Br < I with distances c. 0.02–0.03 Å longer than average values for other [Au(PR3)X] complexes, reflecting steric congestion by the P(mes)3 ligand. For the unsolvated complexes, the Au–X distances are c. 0.02 Å shorter than average values. For the Cl/dmf solvate, both Au–P and Au–X bond lengths increase. For the a complexes, far-infrared spectra show n(Au 35,37 Cl) 336, 329 cm –1 , n(AuBr) 234 cm –1 and n(AuI) 195 cm –1 and solid-state 31 P CPMAS n.m.r. spectra yield broad peaks with d–3.9 (Cl), –0.6 (Br) and +6.0 I). For the Cl/dmf solvate, n(Au 35,37 Cl) are 334, 327 cm –1 and d is –4.4. Solution 31 P n.m.r. spectra in CDCl3 give sharp single peaks at d –5.0 (Cl), –1.4 (Br) and +5.5 (I) with the similarity of the values with those for the solid-state spectra consistent with similar conformational structures for the [Au(P(mes)3)X] molecules in the two states.

Two new bimetallic complexes [Zn(phen)3][Fe(CN)5(NO)] · 2 H2O · 0.25 MeOH, (1) and [(bipy)2(H2O)Zn(μ-NC)Fe(CN)4(NO)] · 0.5 H2O, (2), have been isolated (where phen = 1,10-phenanthroline and bipy = bipyridyl) and characterised by X-ray crystallography [as the 2 H2O · 0.25 CH3OH solvate for (1) and hemihydrate for (2)] infrared spectroscopy and thermogravimetric analysis. Substitution of phenanthroline for bipyridyl resulted in a cyano-bridged bimetallic species rather than two discrete mononuclear metal complexes. The bond angles of Fe-N-O were shown to be practically linear for both 1 [179.2(7)°] and 2 [178.3(3)°], and the Zn atoms have distorted octahedral geometry. The solvent molecules in both crystal lattices take part in forming hydrogen-bonded networks.
