Abstract
An X-ray structure determination of an antiferromagnetic copper complex of p-tert-butyltetrathiacalix[4]arene has shown it to contain a square, phenoxo- and sulfur-bridged cluster of four Cu(II) ions sandwiched between two fully deprotonated calixarenes, thus forming a ditopic, divergent receptor; as prepared, the complex has each cavity occupied by a molecule of dichloromethane.Keywords
