Аннотация

Two new copper(II) complexes [Cu(MEA)2(N3)2] ( 1) and [Cu(BMP)2] (2), where MEA and BMP are 2-morpholin-4-ylethylamine and 2,4-dibromo-6-[(2-morpholin-4-ylethylimino)methyl]phenolate respectively, are prepared and characterized using elemental analysis, FT-IR spectroscopy, and X-ray single crystal diffraction. The crystal of 1 belongs to the triclinic system, space group P-1, with a = 6.661(2) Å, b = 8.440(3) Å, c = 8.913(3) Å, α = 102.032(3)°, β = 107.899(2)°, γ = 98.242(3)°, V = 454.6(3) Å3, Z = 1, Dc = 1.490 g/cm3, R1 = 0.0226, and wR2 = 0.0564. The crystal of 2 belongs to the monoclinic system, space group P21/c, with α = 7.0707(7) Å, b = 15.438(1) Å, c = 14.227(1) Å, β = 96.659(2)°, V = 1542.5(3) Å3, Z = 2, Dc = 1.821 g/cm3, R1 = 0.0437, and wR2 = 0.1041. In each complex, the Cu atom is in a square planar coordination. The molecules of 1 are linked through intermolecular N-H⋯N and N-H⋯O hydrogen bonds to form layers parallel to the ab plane. The molecules of 2 are linked through intermolecular C-H⋯Br hydrogen bonds to form a 3D network.
