The title compound with heteratomic anionic chains 
4134e10002.gif">[Tl4Sb612-] has been discovered in the K-Tl-Sb system.The phase is obtained from a range of compositions near K3TlSb1.5 following reaction first at 750-850 
C andthen at 550 C for one week or more. It crystallizes in the monoclinic system in space group C2/c, Z = 8, a =9.951(1) Å, b = 17.137(3) Å, c = 19.640(6) Å, and 
= 104.26(3). Swing-like (Tl4Sb6)12- units consisting ofalternating Sb and Tl atoms in four- and eight-membered rings are linked through Tl-Tl bonds to form infiniteone-dimensional chains along 
. EHTB calculations and resistivity measurements show that the compound is asemiconductor.
