摘要：

Single-crystal and powder X-ray diffraction data, thermal gravimetric analysis, and infrared spectral data are present for PrKFe(CN)//6 multiplied by (times) 4H//2O. The crystal structure has been determined by single-crystal diffractometry and refined by the least-squares method to yield R equals 0. 0149 and R//w equals 0. 0155. The praseodymium ions are linked nonlinearly to the FeC//6 octahedra by cyanide bridges. Cavities within the structure are occupied by potassium ions and zeolitic water molecules which are within hydrogen bonding distance to the water molecules which are bonded to the nine-coordinated praseodymium ions, PrN//6(H//2O)//3.
