摘要

Two novel dicyanamide complexes [Co(dmf)(2)(NCNCN)(2)] (1) and [Cu(bipy)(NCNCN)]ClO4 (2) have been synthesized and structurally characterized. I crystallizes in the monoclinic space group C2 with a = 13.568(6) Angstrom, b = 7.403(3) Angstrom, c = 8.118(3) Angstrom and Z = 2, whereas 2 crystallizes in the monoclinic system, Cc group, a = 14.270(7) Angstrom, b = 9.143(5) Angstrom, c = 12.371 (1) Angstrom, beta = 118.612(7)degrees, and Z = 4. According to X-ray crystallographic studies, in complex 1 each Co-II ion is six-coordinated with four nitrogen atoms from four mu(1.5)-dca (dca = dicyanamide) ligands and two oxygen atoms from two dmf ligands to form distorted octahedra. 1 forms a 1-D network bridged via mu(1,5)-dca. 2 consists of a uniform Cu(NCNCN)Cu chain, each Cu-II ion is octahedrally coordinated with four nitrogen atoms from two mu(1,5)-dca ligands and one bipy ligand and two oxygen atoms from two ClO4- ions. The octahedral Cu-II ion shows a significant Jahn-Teller distortion, with two axial oxygen atoms considerably farther from the copper than the four equatorial nitrogens. [References: 27]
