Abstract
트리포달 구리(II) 착물 [Cu(pmea)(H2O)](ClO4)2·H2O (1) (pmea=bis[(2-pyridyl)methyl]-2-(2-pyridyl)-ethylamine)을 합성하고 X-선 회절법으로 구조를 규명하였다. 이 착물은 삼사정계, 공간군 P-1, a = 9.9362(9) A, b = 15.7299(17) A, c = 18.0562(11) A, α = 68.760(8)°, β = 76.331(6)°, γ = 77.092(9)°, V = 2526.2(4) A3, Z = 2로 결정화 되었다. 각각의 구리 원자는 약간 일그러진 사각뿔 구조를 갖는데, 바탕 면은 pmea 리간드에 있는 세 개의 질소원자와 물 분자가 포함되어 있으며 축 방향에는 피리딘 고리의 질소 원자가 포함되어있다. 착물 1의 순환 전압전류 그림은 가역 일-전자 산화 CuIII 및 환원 CuI 과정으로 진행됨을 보여주었다. The tripodal copper(II) complex [Cu(pmea)(H2O)](ClO4)2·H2O (1) (pmea = bis[(2-pyridyl)methyl]-2-(2-pyridyl)ethylamine) has been synthesized and structurally characterized by X-ray diffraction method. It crystallizes in the triclinic system P-1 with a = 9.9362(9), b = 15.7299(17), c = 18.0562(11) A, α = 68.760(8), β = 76.331(6), γ = 77.092(9)°, V = 2526.2(4) A3, Z = 2. Each copper atom reveals a distorted square pyramidal with three nitrogen atoms of the pmea ligand and water molecule occupying the basal plane and one nitrogen atom from the pyridine ring according the axial position. The cyclic voltammogram of 1 undergoes reversible one-electron oxidation to the CuIII and reversible one-electron reduction to the CuI.
