| Abstract: | This paper describes the hydrothermal syntheses of two isostructural metal bisphosphonates: M2(O3PC6H4PO3)(H2O)2 M=CoII (1), NiII (2)]. Single-crystal structure determination of compound 1 revealed a pillared layered structure in which the phenyl groups connect the inorganic layers of cobalt phosphonate. Crystal data for 1: orthorhombic, space group Pnnm, a=19.306(5), b=4.8293(12), c=5.6390(14) Å, V=525.7(2) Å3, Z=2. Magnetic susceptibility data indicate that antiferromagnetic interactions are mediated in both cases. |
