摘要：
The nickel (II) complex [Ni(teta){N(CN)(2)}(2)] (teta = 5,7,7,12,14,14-hexamehyl-1,4,8,11-tetraazacyclotetradecane) was synthesized and its structure has been determined by single-crystal X-ray diffraction. Crystal data: C20H36N10Ni, monoclinic, space group P2(1)/c, a = 9.632(2), b = 11.833(2), c = 10.613(2) Angstrom, beta = 93.46(3)degrees, V = 1207.4(4) Angstrom(3), M-r = 475.30, Z = 2, D-c = 1.307 g/cm(3), F(000) = 508, mu(MoKalpha) = 0.831 mm(-1), R = 0.0446 and wR = 0.1274 for 2423 observed reflections with I > 2sigma(I). The center nickel ion is coordinated by six nitrogen atoms, four from the macrocyclic ligand teta and the other two from two dicyanamides. The dicyanamide is coordinated to the metal atoms as uni-dentate manner via nitrile nitrogen atom.
