Compounds of some alkylamido-substituted cyclic tetraamines with copper(II): The structure of di(perchlorato)-RRSS(trans-(6,13-bis(ethylamido)-6,13-dimethyl-1,4,8,11-tetraazacyclotetradecane)copper(II)

摘要

The amino substituents of (trans-6,13-diamino-6,13-dimethyl- 1,4,8,11 -tetraazacyclotetradecane)copper(II) are readily acylated by reaction with acetic or propionic anhydrides to form the 6,13-bismethylamido- (acetylamino-) or 6,13-bis(ethylamido)-(propionylamino-) substituted cations. Centrosymmetrical di(perchlorato-kappa(1)O)-(R-1 (RSS11)-S-4-S-8 -trans-6,13-bisethylamido-6,13-dimethyl-1,4,8,11- tetra azacyclotetradecane-kappa(4) (NNNN11)-N-1-N-4-N-8)copper(II) has copper(II) in square-planar coordination by the endocyclic nitrogen atoms of the macrocycle, Cu-N = 1.996(2), 2.012(2) angstrom, with perchlorate oxygen atoms axially coordinated, Cu-O = 2.528(2) (C) 2005 Elsevier Ltd.
