摘要：

Crystals for x-ray structure determination of NaAl(NH2)4 and NaGa(NH2)4 were obtained by the reaction of the metals with ammonia in autoclaves at 100-degrees-C and P(NH3) = 60 bar within 7 days. The compounds crystallize isotypic in the space group P2(1)/c with Z = 4 NaAl(NH2)4 a = 7.328(2) angstrom, b = 6.047(2) angstrom, c = 13.151(3) angstrom, 8 = 94.04(1)-degrees NaGa(NH2)4 a = 7.4087(8) angstrom, b = 6.0917(5) angstrom, c = 12.855(2) angstrom, beta = 92.10(1)-degrees The structures were refined inclusively all H-positions of the amide ions. The ternay amides are furthermore characterized by their IR spectra and their thermal behaviour.
