The crystal structures of aqua(2,2′-bipyrimidine-N,N')(4,5-dihydroxy-1,2-benzoquinonato-O,O')copper(II) pentahydrate, [Cu(C6H2O4)(C8H6N4)(H2O)].5H2O, containing five-coordinated copper(II) with slightly distorted square-pyramidal geometry and of bis(4,4′- dimethyl-2,2′-bipyridine-N,N')(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.
