Five novel two-dimensional coordination polymers {Fe(4PhPy)(2)[M-II(CN)(4)]}center dot sH(2)O (4PhyPy = 4-phenylpyridine; 1: M-II = Pd, s 0; 2: M-II = Ni, s = 0; 3: M-II = Pt, s = 1) and (Fe(4PhPy)(2)[M-I(CN)(2)](2))center dot sH(2)O (4: M-I Ag, s = 1; 5: M-I = Au, s = 0.5) exhibiting thermal- and light-induced spin-crossover properties have been synthesized and characterized at various temperatures by XANES, EXAFS, PXRD, DSC (techniques), magnetic susceptibility measurements, and Mossbauer spectroscopy.
