摘要
The formation of Co(II) and Ni(II) 3,5-dichlorobenzoates was studied and their compositions and solubilities in water at 293 K were determined (10(-3) mol dm(-3)). The IR spectra of the prepared complexes were recorded and their thermal decomposition in air was investigated. Heated the hydrated complexes lose some water and then decompose to oxides MO. Isostructural complexes with general formula [M(H2O)(6)]L(2) .[ML(2)(H2O)(4)]. 4H(2)O (where L = C6H3Cl2COO-) crystallize in the triclinic system (space group P (1) over bar). The cell parameters for Co(II) complex are: a = 7.36(1) Angstrom, b = 8.55(2) Angstrom, c = 18.05 Angstrom, alpha = 83.1(3), beta = 88.5(3), gamma = 84.8(3)degrees, V = 1122.4(4) Angstrom(3), Z = 1, D-c- 1.645 mg/m(3), D-m = 1.65 mg/m(3) and for Ni(II) one: a = 7.33(2) Angstrom, b = 8.51(3) Angstrom, c = 18.04(5) Angstrom, alpha = 82.6(3), beta = 88.1(3), gamma = 84.7(3)degrees, V = 1108(4) Angstrom(3), Z = 1, D-c = 1.662 mg/m(3), D-m = 1.66 mg/m(3).
