摘要：

The suitability of the stilbazole push-pull ligands, 4'-dimethylaminostilbazole (DMAS) and 4'-diethylaminostilbazole DEAS), for the construction of bimetallic Fe-II-Ag-I/Au-I cyanide-based coordination polymers that exhibit spin crossover properties is investigated. The structural and physical characterization of four novel two-dimensional Fe-II polymers formulated as {Fe(DMAS)(2)[Ag(DMAS)(CN)(2)](2)} (1) and {Fe(L)(2)[M(CN)(2)](2)} (L=DMAS, M=Au (2); DEAS, Ag (3); DEAS, Au (4)) is reported. Polymers 1 and 4 are paramagnetic over the whole range of temperatures studied (5-300 K), whereas 2 and 3 exhibit spin crossover properties.
