TheCrystal Structures of Bis(2-aminoethyl 2-pyridyl sulfide)Copper(II) Perchlorate and Bis(2-aminoethyl 2-pyrid y l sulfoxide)-copper(II) Perchlorate

Abstract

The violet bis(2-aminoethyl 2-pyridyl sulfide)cppper(II) perchlorate [1] and blue bis(2-aminoethyl 2-pyridyl sulfoxide)copper(II) perchl3fate [2] were synthesized and have been characterized by means of X-ray crystallography. The Cu(II) atom in 'the cation o[1] is located at the center of symmetry and has a square-planar coordination by 4 N atoms. The S atom in Cu-NH₂CH₂CH₂S-C-N ring lies in the position near to the axial site. The Cu…S distance is 2.832(1) Å and the Cu→S vector intersects the coordination plane at 59.8°. The Cu atom in the centrosymmetric cation of [2] has an elongated octahedral coordination by 4 N (equatorial) and 2 O atoms (axial). The Cu-O distance is 2.301(7) Å.
