Abstract
Crystals of K(Mg0.5Zr0.5).(MoO4)2 were grown, and the composition and crystal structure of the compound were refined in an X-ray diffraction study (CAD-4 automatic diffractometer, MoKα radiation, 475 F(hkl), R=0.022). The parameters of the trigonal unit cell are: a=5.763(1); c=7.187(1) Å,Z=1, space group P3m1. A typical feature of a glaserite-like structure is atomic arrangement in two layers: at z=0 the Mg and Zr atoms are statistically distributed in the oxygen octahedra, and at z=0.5 the K atoms are distributed inside the icosahedra. In the second layer, Mo atoms with tetrahedral environment are also distributed.
