✦ Synopsis

] n 1 has been synthesized and structurally characterized. Compound 1 is monoclinic, P2 1 / c with unit cell parameters a = 8.8759(9) Å, b = 11.4112(11) Å, c = 8.8908(9) Å, b = 106.010(6)°, V = 865.6(1) Å 3 , Z = 2 and D calc. = 1.600 g cm À3 . The structure refined to R 1 = 0.0245, wR 2 = 0.0626 for all 2014 unique reflections and 152 parameters; GooF = 1.056. It consists of a polymeric chain of nearly octahedral Ni 2+ centers bridged by bidentate fumarato ligands. Non-covalent interactions lead these chains to aggregate into an interesting metallosupramolecular assembly. Indexed PXRD pattern, solid state UVvis-NIR spectral data, thermogravimetric behavior and variable temperature magnetic susceptibility data on 1 are presented.
