New oxozincates of alkali metals: Rb2[ZnO2] and Cs2[ZnO2]
Description
Colorless single crystals of the hitherto unknown Rb2[ZnO2] (a = 9.55, b = 6.33, c = 15.91 A, β = 118.60, z = 8, dsub(pyk) = 4.11, dsub(roe) = 4.21 g . cm-3) and Cs2[ZnO2] (a = 9.85, b = 6.61, c = 16.26 A, β = 116.80) have been prepared, which crystallize monoclinic, P21/c -Dsub(2h)5. Unexpected there are 'isolated' groups [Zn4O8]. Half of the Zn atoms exhibit the unusual coordination number 3 towards O2-. The Madelung Part of Lattice Energy, MAPLE, and the Effective Coordination Number, ECoN, the latter by means of Mean Fictive Ionic Radii, MEFIR, are calculated and discussed. (author)
