The 1D {[CuII(cyclam)]3[WV(CN)8]2.5H2O}n (1·5H2O) (cyclam = 1,4,8,11-tetraazacyclotetradecane) coordination polymer of ladder topology can be obtained in water-alcohol solution from [Cu(cyclam)]2+ and [W(CN)8]3− building blocks. Upon dehydration, 1·5H2O undergoes a single-crystal-to-single-crystal structural transformation to the anhydrous {[CuII(cyclam)]3[WV(CN)8]2}n (1) form, which retains the same topology, but is characterized by shorter Cu-W distances and significantly more bent CN-bridges. The deformation of the coordination skeleton is reflected in magnetic properties: the predominant intra-chain interactions change from ferromagnetic in 1·5H2O to antiferromagnetic in 1. The reaction between the same building blocks in water solution under slow diffusion conditions leads to the formation of a 0D {[CuII(cyclam)(H2O)]2[CuII(cyclam)][WV(CN)8]2}.3H2O pentanuclear assembly (2·3H2O).

AbstractThe neutral, four-fold protonated pyridine-3,5-dicarbox(3,5-dicarboxylatoanilide) (H4L) reacts with Mn(II) salts under hydrothermal conditions to yield a new complex: [Mn2(L)(H2O)2]·H2O (1), which has been characterized by single crystal X-ray diffraction, infrared spectroscopy, and elemental and thermogravimetric analyses. Complex 1 exhibits a binodal (4,8)-connected 3D framework with flu (412.612.84)(46)2 topology. The magnetic properties of 1 were investigated.

The coordination polymer [Cu3(tci)2(phen)2] n (H3tci = 1,3,5-tris(2-carboxyethyl)isocyanurate; phen = 1,10-phenanthroline) has been synthesised. Single-crystal X-ray diffraction studies have shown that the polymer displays a 2-D metal–organic framework based on linear trinuclear copper cluster units, and its magnetic properties indicate antiferromagnetic interactions.
