Abstract
The crystal structures of (4,5-dihydroxy-1,2-benzoquinonato-O,O')coppe r-(II) pentahydrate, [CU(C6H2O4)(C8H6N4)(H2O)].5H(2)O, containing five -coordinate copper(II) with slightly distorted square-pyramidal geomet ry, and )(4,5-dihydroxy-1,2-benzoquinonato-O,O')nickel(II) monohydrate , [Ni(C6H2O4)-(C12H12N2)(2)].H2O, comprising six-coordinate nickel(II) with distorted octahedral geometry, are reported. In both complexes, the dianion of 2,5-dihydroxy-1,4-benzoquinone occurs in the bidentate o-benzoquinone form which chelates through the 1,2 O atoms.
