Abstract
Cd3[Cr(CN)6]2 · 14H2O crystallizes in a cubic unit cell, space group Fm3m(Oh5, No. 225), with a0 = 10.961(2)Å. The observed density is 1.70(1) Mg-m−3 (calculated density, 1.690 Mg-m−3). A thermogravimetric analysis has yielded 13.9(2) water molecules per formula unit. X-Ray fluorescence emission energy values and infrared spectroscopic results are presented. Full-matrix least-squares refinement of 160 unique reflections has yielded R1 = 0.0350 and R2 = 0.0349. The disordered structure contains molecules in the unit cell. Linkage of the divalent Cd atoms to the Cr atoms is accomplished by cyanide bridging. A new structural model was employed and important bond distances are reported.
