Abstract: 
By heating of well ground mixtures of the binary oxides As2O3, Na2O, and Li2O2, molar ratio As: Na: Li = 1.0: 1.0: 2.0, in a well closed Ni tube (650-degrees-C, 21 d) colourless single crystals of NaLi2[AsO4] were obtained for the first time. The new orthoarsenate(V) crystallizes orthorhombic (space group P mn2(1)-C2v7, No. 31) with Z = 2. The structure determination showed that it is isostructural to beta(II)-Li3[VO4] and that means the Li3[PO,]-type. The lattice constants a = 702.9(2) pm, b = 520.5(1) pm, c = 505.4(2) pm were taken from Guinier-Simon powder data. The structure was determined by four-circle diffractometer data [Philips PW 1100, AgKalphaBAR, 679 independent out of 2373 I(o)(hkl), R = 3.03%, R(W) = 2.29%; parameter 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.
