摘要:
The crystals of [(CH2)(6)N-4(C3H5)]Cu2Cl3 (1), [(CH2)(6)N-4(C3H5)]Cu2Cl3 (II), and [(CH2)(6)N-4(C3H5)]CuCl2 (III) complexes were electrochemically synthesized (ac) from CuCl2 . 2H(2)O and N-allylhexamethylenetetraminium chloride in ethanol solutions at pH 6, 4.5, and 3. Their structures were determined using X-ray diffraction analysis (DARCh diffractometer, MoKalpha radiation, theta/2theta scan mode). Complex I crystallizes in the monoclinic system: space group A2/a, a = 24.812(6) Angstrom, b = 8.855(3) A, c = 12.080(2) Angstrom, gamma = 89.21(3)degrees, and Z = 8. Complex H crystallizes in the triclinic system: space group P (1) over bar, a = 7.618(2) Angstrom, b = 7.048(2) Angstrom, c = 13.150(3) Angstrom, alpha = 97.50(2)degrees, 92.70(2), gamma = 100.74(2)degrees, and Z = 2. The crystals of complex III are orthorhombic: space group Pmn2(1), a = 7. 478(2) Angstrom, b = 8.827(2) Angstrom, c = 9.662(3) Angstrom, Z = 2. The organic cation in complex I acts as a tridentate pi,sigma,sigma-ligand; that in complex II, as a bidentate pi,sigma-ligand. In complex III, the organic cation is involved in coordination with the copper(l) atom only through one nitrogen atom.
