The compound Na{sub 3}SbTe{sub 3} has been synthesized from the elements and characterized by single crystal X-ray diffraction. Na{sub 3}SbTe{sub 3} is cubic, crystallizing in the cP28 structure type (isomorphous with Na{sub 3}AsS{sub 3}); space group P2{sub 1}3 (No. 198); a=9.6114(9) {angstrom}; Z = 4; R1 = 0.0324; wR2 = 0.0561 (I {le} 2{sigma}(I)). The structure consists of isolated sodium cations and trigonal pyramidal [SbTe{sub 3}]{sup {minus}3} anions with a Sb-Te bond length of 2.787(1) {angstrom} and a Te-Sb-Te bond angle of 100.0(1){degrees}. The structure is related to both the Li{sub 3}Bi and K{sub 3}AsS{sub 4}-type structures. Both lattice energy and semiempirical electronic structure calculations are utilized to evaluate various local and long-range structural aspects of this Zintl phase.
