Conformational influences in copper co-ordination compounds. Part III. Crystal structure of the p-nitrophenol adduct of NN′-ethylenebis(salicylideneiminato)copper(II)

Abstract

A three-dimensional X-ray investigation of the dark red p-nitrophenol adduct of NN′-ethylenebis(salicylideneiminato)copper(II) has revealed a hydrogen bonding association between phenolic and donor oxygen atoms. The adduct is monomeric, four-co-ordinate and essentially planar, in contrast with its dimeric five-co-ordinate nature in the solid when other species are absent. As a result of the planarity the buckling of the ethylene bridge (carbons 0·20 and –0·28 Å from the co-ordination plane) is much more symmetrical than that found in similar molecules. There are two molecules of adduct in a triclinic unit cell of dimensions: a= 7·95, b= 11·72, c= 14·67 Å, α= 130·3, β= 96·4, γ= 95·0°. The space group proved to be P[1 with combining macron].
