摘要：

Solvothermal synthesis of FeCl2 center dot 4H(2)O and H2C2O4 center dot 2H(2)O in methanol at 120 degrees C yielded yellow plate-like crystals of [Fe(C2O4)(CH3OH)](n). Each iron atom is in a distorted octahedral environment, being bonded to four oxygen atoms from two bisbidentate oxalate anions, one O atom of a chelating oxalate anion and one O atom from a methanol molecule as an oxalate group bridging ligand in a five-coordination mode. The neutral layer of [Fe(C2O4)(CH3OH)](n) with a [4,4] net along the ac plane. There is no interaction between layers. A long range magnetic ordering with spin canting at T-N approximate to 23 K was observed and confirmed by AC susceptibility measurements.
