Abstract:
Compounds [M(2)(4-pi)(H(2)O)(4)]·1.5H(2)O [M(II) = Mn(1), Co(2), Ni(3)] and a heterometallic analogue [Co(1.14)Ni(0.86)(4-pi)(H(2)O)(4)]·1.5H(2)O (4) have been synthesized utilizing a rigid 4-phosphonoisophthalic acid (4-piH(4)). 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 {MO(6)} 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.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
