Abstract

The reaction of $[Cu(L)]Cl_2{\cdot}H_2O(L=3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,0^{1.18},0^{7.12}]docosane)$ with 2,5-pyridinedicarboxylate(pdc) led to the formation of $[Cu(L)(H_2O)](pdc){\cdot}6H_2O(1)$. The structure was characterized by X-ray crystallography and spectroscopic method. The coordination geometry around the copper atom is a distorted square-pyramid with four secondary amines of the macrocycle occupying the basal sites and a water molecule at the axial position. Intermolecular hydrogen bonds in 1 form a three-dimensional molecular network.

$[Cu(L)]Cl_2{\cdot}2H_2O(L=3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,0^{1.18},0^{7.12}]docosane)$과 2,5-pyridinedicarboxylate(pdc)의 반응으로부터 $[Cu(L)(H_2O)](pdc){\cdot}6H_2O(1)$가 합성되었다. 화합물 1의 구조가 X-ray 회절법 및 분광학적 방법으로 규명되었다. 중심 copper 원자는 거대고리 리간드로부터 4개의 이차 아민과 축방향 위치의 물분자로 결합된 약간 일그러진 사각뿔 구조를 갖는다. 또한 분자간 수소결합은 삼차원의 분자구조를 형성한다.
