| Abstract: | Summary Complexes of allopurinol (apH) with FeIII and several 3d metal(II) (e.g. Fe, Co, Ni and Cu) perchlorates were prepared. The solid complexes isolated included two monomeric hexacoordinated adducts of the type Fe(apH)3-(OClO3) (OH2)2]ClO4 and Fe(apH)3(OClO3)2(OH2)]ClO4, involving N(8)-bound neutral apH ligands, and polymeric Co, Ni or Cu complexes containing both neutral apH and monoanionic ap- ligands. The latter three complexes involved both N(8)-bound terminal apH and N(1), N(8)- or N(1), N(9)-bound bridging ap- ligands, and were of the following types: (apH)2Cu(ap)]
