The reaction of ((eta5:eta1-C5H4CH2CH2OMe)ZrCl2(mu-Cl))2 (1) with several solvents, particularly with water, was studied. The bidentate coordination of the C5H4CH2CH2OMe ligand in 1 was retained chloroform, dichloromethane, benzene, acetone, thf and acetonitrile. The coordination of the ether side chain was reversibly broken in methanol and water. A thf solvate of 1 was structurally analyzed. Reaction of wet DMSO produced the salt ((eta5:eta1-C5H4CH2CH2OMe)ZrCl2(H2O)(DMSO)2)(C) in which the ether side-arm was not coordinated.

Dinuclear copper complexes containing tridentate dinucleating ligands are prepared and considered as structural and functional models for catechol oxidases. In these complexes, the Cu(II) centers undergo antiferromagnetic coupling. The crystal structure of the complexes remain unchanged in the methanolic solution. The copper complex of 1,5-bis(2-benzimidazolyl)-3-pentanol exhibits catecholase activity by oxidizing 3,5-di-tert-butylcatechol to quinone.
