摘要：

Single crystals of SmFe(CN)//6 multiplied by (times) 4H//2O prepared from an aqueous solution under ambient conditions have been used for single-crystal diffraction, thermal gravimetric analysis, and infrared spectrometric studies. This characterized compound is compared to previously reported LnT(CN)//6 (T equals Cr, Fe, Co) structures. Samarium hexacyanoferrate (III) tetrahydrate is found to be monoclinic, not hexagonal or orthorhombic as presupposed. SmFe(CN)//6 multiplied by (times) 4H//2O crystallizes in space group P2//1/m (No. 11), a equals 7. 431(1), b equals 13. 724(3), c equals 7. 429(2) Angstrom, beta equals 119. 95(1) degree , Z equals 2. Full-matrix least-squares refinement has yielded the final values of R equals 0. 0292 and R//w equals 0. 0296 for 1028 unique reflections. The observed and calculated densities are 2. 198(3) and 2. 197 Mg m** minus **3, respectively.
