  Reactions of Cd(OAc)2·2H2O with variously substituted pyridines. Efforts to unravel the factors that determine structure/nuclearity of the products

  摘要：

  The reactions of Cd(OAc)(2)center dot 2H(2)O with variously substituted pyridines in methanol afforded unique one-dimensional coordination polymers (1D CPs), [Cd-2(mu(2)-kappa(2):kappa(1)-OAc)(2)(mu(2)-kappa(1):kappa(1)-OAc)(2)L-2] (L= NC5H5 (1), NC5H4Me-3 (2), and NC5H3Me2-3,5 (3)) and [Cd-3(mu(3)-kappa(1):kappa(2)-OAc)(3)(mu(2)-kappa(2):kappa(1)-OAc)(2)(NC5H3Me2-3,4)(2)] (4), and discrete and bimolecular complexes, [(Cd(OAc)(2)(NC5H3Me2-3,4)(2)(H2O)(2)] (5), [Cd(kappa 2-OAc)(2)(NC5H4Me-4)(2)(H2O)]center dot[Cd(kappa 2-OAc)(2)(H2O)(2))] (6), [Cd(kappa(2)-OAc)(2)L2L']center dot xH(2)O (x = 0, L' = H2O, L = NC5H4 (OMe)-4 (7); (NC5H4Bu)-Bu-t-4 (8); x = 2, L = L' = NC5H4(NMe2)-4 (9 center dot 2H(2)O)). The products were characterised by elemental analysis, IR, solution NMR (H-1 and C-13), solid-state CP-MAS C-13{H-1} and Cd-113 NMR, TGA/DTA analyses, and single crystal X-ray diffraction. Phase purity of 1-4 was verified by powder Xray diffraction (PXRD). Plausible mechanisms of formation of the products are proposed based on a point zero charge model. 4 represents the first cadmium containing 1D CP that possesses a tridentate bridging (mu(3)-kappa(1):kappa(2)) acetate coordination mode and 6 represents the first structurally characterised bimolecular cadmium(II) complex containing two different neutral cadmium(II) coordination species per formula unit. 9 center dot 2H(2)O was calcined at 500 degrees C to afford CdO as confirmed by PXRD and the morphology of CdO was studied by scanning electron microscopy.

• The preparation and structural characterisation of bis(N,N-diethylmonothiocarbamato)complexes of cadmium and of the novel tetrameric complex [Et4Zn4(OSCNEt2)2(NEt2)2]: two new bonding modes for the monothiocarbamato ligand

  Bis(diethylmonothiocarbamato) complexes of cadmium (1) and zinc (2) were prepared by the reaction of sodium monothiocarbamate with cadmium acetate or zinc chloride. Compound 1 crystallises as clear needles and a single crystal X-ray analysis showed it to be monoclinic (space group C2/c, no. 15), a = 22.143(2), b = 9.239(2), c = 7.553(3) Å, β = 101.41(2)° and Z = 4. The coordination at the cadmium centre is distorted trigonal prismatic with two S,O-bidentate and two O-monodentate diethylmonothiocarbamato ligands. This new, O-binucleating, bonding mode for the monothiocarbamato ligand results in polymeric chains which are co-aligned to give a distorted close-packed hexagonal array.The cage complex [Et4Zn4(OSCNEt2)2(NEt2)2] 3 is formed as the only isolable product from the reaction of EtZnNEt2 with carbonyl sulfide. Clear rhombic crystals (space group P21/n, no. 14) were formed [a = 10.818(1), b = 14.732(1), c = 11.758(2) Å, β = 103.25(1)° and Z = 2]. The cage is comprised of two six-membered Zn2CNOS metallocycles that are linked by pairs of Zn–S and Zn–O bonds. In 3 a second new bonding mode for the monothiocarbamato ligand is observed in which both the oxygen and sulfur atoms are binucleating. Molecules of 3 pack to form a slightly distorted cubic close-packed array. The variable temperature 1H NMR of 3 is also reported and shows the cluster to remain intact in solution.
