AB  - Complex formation of copper(II) bromide and acetate with 1-carboxamide-3,5-dimethylpyrazole (HL3) and copper(II) bromide with 5-amino-4-carboxamide-1-phenylpyrazole (L-2), 4-acetyl-3-amino-5-methylpyrazole (HL4) and 1-carboxamidine-3,5-dimethylpyrazole (HL5), was studied. The obtained compounds, CuBr2(L-2)(2), Cu(L-3)(2), CuBr2(HL4)(2), CuBr2(HL5)(2) and [CuBr(HL1)(L-3)](2) (HL1 denotes the 3,5-dimethylpyrazole), are characterized by elemental analysis, FT-IR spectrometry, molar conductivity, TG-MS and DSC. The X-ray structure of [CuBr(HL1)(L-3)](2) and Cu(L-3)(2) is discussed. For [CuBr(HL1)(L-3)](2) a dimeric penta-co-ordinated structure has been found; the co-ordination around the metal in Cu(L-3)(2) is trans-square planar. To CuBr2(L-2)(2) and CuBr2(HL4)(2) a nearly tetrahedral, while for CuBr2(HL5)(2) an octahedral geometry may be assumed. It means that the geometry of the compounds in the first place depends on the ligand substituents. The course of the complex formation reaction is anion-dependent and may be explained on the basis of Pearsons theory, taking into account the steric factors. A low stability intermediate formation was observed in the thermal decomposition of Cu(L-3)(2). (C) 2003 Elsevier B.V. All rights reserved.
