摘要

X-ray single crystal data for K2Zn(NH2)(4) allowed the determination of the so far unknown positions of the protons: , Z=2, a=6.730(1) Angstrom, b=7.438(1) Angstrom, c=8.019(2) Angstrom, alpha=72.03(2)degrees, beta=84.45(2)degrees, gamma=63.82(1)degrees, Z(F-o) with (F-o)(2) greater than or equal to 3 sigma(F-o)(2)=2166, Z(parameters)=96, R/R-w=0.032/0.039. In the structure of K2Zn(NH2)(2) the amide ions are nearly hexagonal close packed. One layer of octahedral holes paralIel to (010) is fully occupied by potassium atoms and zinc is in an ordered way in a quarter of the tetrahedral holes of the next layer. The orientation of the protons of the amide ions is characteristic for this type of structure (filled up CdI2 type). [References: 19]
