Abstract

A hydrothermal reaction of a mixture containing iron(II) oxalatedihydrate, phosphor-us acid, piperazine, and water at 150 degrees C for72 h gave light-yellow cubes of a new hybrid iron oxalate-phosphite,$[C_4N_2H_1_2][Fe^I^I_4(HPO_3)_2(C_2O_4)_3]$ , I. The structure, formed by $Fe_O_6, HPO_3$, and oxalate building units, possesses infiniteone-dimensional chains of Fe-O-Fe, formed by $Fe_2O_1_0$ dimers. The phosphite units are grafted to these chains, and the oxalate moietiesbond with the iron center through in-plane and out-of-planeconnectivity forming a three-dimensional structure with intersectingchannels. The organic amine molecule occupies the middle of thechannels. The connectivity between the phosphite units and the Fe-O-Fechains resembles the tancoite structure. Magnetic investigations revealthat the iron is present in the +2 oxidation state and ordersantiferromagnetically.
