Abstract

The reaction of CdCl2 center dot 2.5H(2)O with two equiv of aq. NaOH followed by treatment of the resulting solution with two equiv of pivalic acid gave Cd(kappa(2)-OC(O)Bu-t)(2) (H2O)(2)] (1) in 83% yield while the aforementioned reaction with Cd(OAc)(2)center dot 2H(2)O as Cd2+ source afforded a trinuclear heterobimetallic 1D-CP, {Na-2Cd(mu(5)-kappa(3):kappa(3)-OAc)(mu(3)-kappa(2):kappa(3) OC(O)Bu-t)(mu(3)-kappa(1):kappa(2)-OC(O)Bu-t)(2)]center dot 2(t)BuC(O)OH}(infinity) (2) in 90% yield. Complexes 1 and 2 were characterized by elemental analyses, IR spectroscopy, solution H-1 and C-13 {H-1} NMR spectroscopy and solid state CP-MAS C-13{H-1} NMR spectroscopy, TG-DTA analyses and single crystal X-ray diffraction. The phase purity of 2 was also verified by powder X-ray diffraction. Complex 1 represents the first structurally characterised discrete mono-nuclear cadmium(II) carboxylate complex which is known to contain a pair of chelating carboxylate ligand, while 2 represents the first structurally characterized trinuclear heterobimetallic 1D-CP formed through aggregation via covalent coordinate bond.
