Abstract

The crystal structure of Cu(pta)(2) . Phen has been determined. The phenanthroline ligand occupies a position in the equatorial plane of the tetragonally distorted octahedron with equal Cu-N distances and equivalent beta-diketonate-anions. Cu(pta)(2) . 2,2'-Dipy is isostructural to Cu(pta)(2) . Phen. The volatility of adducts decreases in the sequence Cu(thd)(2) . Phen, Cu(pta(2)). Phen and Cu(hfa)(2) . Phen changing inversely to that of the beta-diketonates. The variation of packing mode caused by the difference of the molecular structure is considered to be responsible for the effect. The changes of the electronic spectra of copper(II) beta-diketonates caused by adduct formation are discussed. (C) 1997 Elsevier Science Ltd.
