摘要:
Two new mononuclear bromido-coordinated complexes, [ZnBr2L1] (1) and [CuBr2L2] (2), where L-1 = 2-[2-(1-pyridin-2-ylethylideneamino)ethylamino] ethanol and L-2 = N'-(1-pyridin-2-ylethylidene) ethane-1,2-diamine, have been synthesized and structurally characterized by IR spectra and X-ray crystallography. Complex (1) crystallizes in the orthorhombic space group Pbca with unit cell dimensions a = 15.146(3) angstrom, b = 11.400(2) angstrom, c = 17.350(3) angstrom, V = 2995.7(9) angstrom(3), Z = 8, R-1 = 0.0469, and wR(2) = 0.0909. Complex (2) crystallizes in the monoclinic space group P2(1)/n with unit cell dimensions a = 9.041(1) angstrom, b = 14.994(2) angstrom, c = 9.202(1) angstrom, beta = 99.352(3)degrees, V = 1230.8(3) angstrom(3), Z = 4, R-1 = 0.0290, and wR(2) = 0.0580. The Zn atom in (1) is five-coordinate in a trigonal-bipyramidal geometry, and the Cu atom in (2) is five-coordinate in a square pyramidal geometry.
