Abstract

The complex [Ni(L)](BDC)·4H₂O (1) (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[16,4,O/sup 1.18/,O/sup 7.12/] docosane; BDC = 1,3-benzenedicarboxylate) has been synthesized and characterized by X-ray crystallography. Compound 1 crystallizes in the orthorhombic space group Pcnb, with a = 8.764(2) , b = 17.687(2) , c = 19.475(1) , V = 3018.7(8) ³, Z = 4, R₁, (wR₂) for 2148 observed reflections of [1>2σ(I) was 0.0822 (0.2236). Compound 1 is interconnected to give a three-dimensional network through weak hydrogen-bonding interactions.

[Ni(L)](BDC)·4H₂O (1) (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[16,4,O/sup 1.18/,O/sup 7.12/]docosane;BDC = 1,3-benzenedicarboxylate) 착물을 합성하고 구조를 규명하였다. 이 착물은 사방정계, 공간군 Pcnb, a = 8.764(2) , b = 17.687(2) , c = 19.475(1) , V = 3018.7(8) ³, Z = 4로 결정화 되었다. 이 착물의 구조는 최소자승법으로 정밀화하였으며, 최종 신뢰도 R₁(wR₂)값은 2148개의 회절반점에 대하여 0.0822 및 0.2236이었다. 화합물 1은 수소결합들로 연결된 삼차원의 그물 구조를 갖는다.
