Dimeric copper(II) 2-methyl-2-phenylpropanoate adducts with water or 2,6-lutidine and a monomeric copper(II) triphenylacetate adduct with 2,6-lutidine

Abstract

The structures of diaquatetrakis(μ-2-methyl-2-phenylpropanoato-O:O'')dicopper(II), (Cu(C 10 H 11 O 2 ) 2 -(H 2 O)] 2 (I), bis(2,6-dimethylpyridine)tetrakis(μ-2-methyl-2-phenylpropanoato-O:O')dicopper(II) benzene solvate, (Cu(C 10 H 11 O 2 ) 2 (C 7 H 9 N)] 2 .C 6 H 6 (II) and trans-bis(2,6-dimethylpyridine)bis(triphenylacetatoO, O')copper(II), (Cu(C 10 H 15 O 2 ) 2 (C 7 H 9 N) 2 ] (III), have been determined by single-crystal X-ray diffraction. (I) and (II) are dinuclear Cu II complexes having cage structures and the coordination geometries around the Cu atoms are square pyramidal in (1) and distorted trigonal bipyramidal in (II)
