| 摘 要： | 1 INTRODUCTION Crystal engineering is becoming an increase- ingly interest field by means of coordinated co- valent bonding or supramolecular contacts (such as hydrogen bonds, p-p interaction etc.)[1～7]. The ligand [N(CN)2]- is a remarkably versatile building block for constructing supramolecular architectures since it may act in uni-, biand tridentate manner. Additional ligands, such as coordinating amines (Lewis bases), in combination with dicyan- amide have been shown to produce n…

Synthesis and Crystal Structure of Bis(dicyanamide) (5,7,7,12,14,14-Hexamethyl- 1,4,8,11-tetraazacyclotetradecane) Nickel(Ⅱ) |

| Abstract: | 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 P21/c, a = 9.632(2), b = 11.833(2), c = 10.613(2) ? b = 93.46(3), V = 1207.4(4) ?, Mr = 475.30, Z = 2, Dc = 1.307 g/cm3, F(000) = 508, m(MoKa) = 0.831 mm-1, R = 0.0446 and wR = 0.1274 for 2423 observed reflections with I > 2s(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. |
