摘要

Abstract

A copper(II) complex based on N-(2-pyridylmethyl)iminodiethane sulfonic acid is synthesized for the first time, and its structure is analyzed by single crystal X-ray diffraction (CCDC deposit No. 2431746). The coordination polymer is formed by [(Cu2L2(H2O)2)·6H2O]n monomer links in which the octahedral coordination environment of the metal center is composed of nitrogen atoms of pyridine and the amino group and oxygen atoms of the sulfo group and the water molecule, which are located in the equatorial plane. The axial positions contain oxygen atoms of the sulfo group of the adjacent ligand and the neighboring molecule, which form the 1D coordination polymer. The Cu⋯Cu distances between the nearest atoms of the coordination polymer is 5.273 Å, and the second nearest copper atom is at a distance of 5.313 Å. Unit cell parameters are: a, b, c = 11.2986(5) Å, 21.3011(8) Å, 7.4884(4) Å; α, β, γ = 90.00°, 108.993(6)°, 90.00°.
