Up to now, three polymorphs of FeC2O4·2H2O have been reported in the literature. One of them belongs to monoclinie system. The cell parameters are: a=12.05, b=5.57, c=9.76, β=124°18′, and its space group is C2/c. It is called a-FeC2O4·2H2O. Both of the other two belong to orthorhombic system. Their cell parameters and space groups are: a=12.26, b=5.57, c=15.48, Cccm, and a=11.78, b=15.46, c=5.56, Fmm2. The former is β-Fe C2O4·2H2O.展开更多
