Abstract

Compounds [M2(4-pi)(H2O)4]·1. 5H2O [M(ii) = Mn(1), Co(2), Ni(3)] and a heterometallic analogue [Co1.14Ni0.86(4-pi)(H2O)4]·1. 5H2O (4) have been synthesized utilizing a rigid 4- phosphonoisophthalic acid (4-piH4). Compounds 1-4 are isostructural, confirmed by their powder XRD measurements. Single crystal structural determinations of 1 and 2 reveal that these compounds display a novel pillared layered open framework structure with zeolite gismondine (GIS) topology. Within the layer, edge-sharing {MO6} octahedra are found, which are connected by carboxylate and phosphonate groups along the c- and b-axis, respectively. Dominant antiferromagnetic interactions are propagated between the magnetic centers in 1, 2 and 4. While in 3, ferromagnetic exchange couplings are observed.
