摘要：

Rietveld analyses of the neutron powder diffraction patterns of Ni(NH3)2Ni(CN)4.2C6D6 and Zn(NH3)2-Ni(CN)4.2C6H6 have been performed. The space group P4/m is confirmed for Ni(NH3)2-Ni(CN)4.2C6D6 with a = 7.2196, c = 8.1007 angstrom at 25 K, a = 7.2358, c = 8.3104 angstrom at 300 K. The same space group is found for Zn(NH3)2Ni(CN)4.2C6H6 with a = 7.3294, c = 8.0722 angstrom at 25 K. The effects of quantum free-rotation of the NH3 groups is seen clearly in the temperature factors of the ammine protons.
