Abstract

Bis (1, 1, 1-trifluoro-5, 5-dimethyl-5-methoxy-acetylacetonato) copper (II) was prepared in two polymorphic modifications. The orthorhombic α-form is stable and densely packed, with four trans and four cis square bischelate building blocks per unit cell. These are connected through additional coordination bonds to form a dense polymer network. For the trigonal β- form, the square bischelate complex units are present exclusively as the trans isomers. ...
