Abstract
The crystal structure of a solvate [Zn(НL)Cl]×EtOH is determined by single crystal X-ray crystallography (150 K, Bruker X8 Apex CCD autodiffractometer, МоKa radiation). The crystals are triclinic, unit cell parameters are: a = 7.4755(4) Å, b = 13.9701(11) Å, c = 14.4593(19) Å, α = 82.277(2)°, β = 75.410(2)°, γ = 75.356(1)°, space group Р1. The structure of the solvate contains two crystallographically independent complex [Zn(НL)Cl] molecules and two non-coordinated ethanol molecules. In each of the molecules, Zn2+ ions coordinate N atoms of tetradentate chelating ligands НL– and a Cl atom. ClN4 polyhedra have a distorted tetragonal pyramidal geometry. EtOH molecules make H-bonds with the complex molecules, thus facilitating the formation of chains along the х axis.
