摘要
Two complexes, [ Cu （salpn） ] · NH （ CH3 ）2 （ 1 ） and [Ni （ salpn ）·H20] （ 2 ） （ H2 salpn = N, N-bis（salicylidene）-propane-1,3-diamine） were characterized by IR, element analysis and single crystal X-ray diffraction analysis. Crystal data for complex 1 ： monoclinic, P21/C, a = 1. 097 4×10^-7 cm, b=1.4806x10-7 cm, c=1.0315×10^-7 cm, β=94.43（3）°. The Cu （II） ion in complex 1 is four coordinated with distorted square planar coordination geometry. The crystal structure of com- plex 1 consists of [ Cu（salpn）] coordination complex and a guest molecule NH（ CH3 ）2 that can act as both H-bonding donor and acceptor and plays an important role in constructing supramolecular ar- chitecture. Crystal structure data for complex 2： orthorhombic, Pnma, a = 8. 676 3 ×10^-8 cm, b = 2. 414 5 ×10^-7 cm, c = 7. 538 8×10^-8 cm. The Ni（II） ion in complex 2 is five-coordinated with a but- terfly coordination geometry. The coordinated water molecule plays a key role in hydrogen-bonded networks.
