Abstract: 
By heating of well-ground mixtures of the binary oxides ("Cs2O", Na2O2, As2O3; Cs:Na:As = 2:1:1; Ni-tube, 500-degrees-C, 21 d) bright, colourless single crystals were obtained for the first time. The new arsenate crystallices monoclinic (space group P2(1)/m) with a = 827,5(2), b = 615,7(2), c = 605,6(2) pm, beta = 91,98(2)-degrees (Guinier-Simon powder data), Z = 2. It is isotypic with Cs2Na[VO4] [2]. The structure was determined by four-circle-diffractometer data [Siemens AED II, MoK-alphaBAR, 1155 I(o) (hkl), R = 5.1%, R(w) = 4.4%, parameters see text]. The Madelung Part of Lattice Energy, MAPLE, and Effective Coordination Numbers, ECoN, these calculated via Mean Fictive Ionic Radii, MEFIR, are calculated and discussed.
