The　title　compound　has　been　synthesized　by　high-temperature　solid　state　reaction.　The　crystal　structure　was　determined　by　single　crystal　X-ray　diffraction　method.　The　crystal　belongs　to　orthorhombic　system　with　space　group　Pnma,　Z=4,　a=6.480(1),　b=3.5839(6),　c=16.994(4)　angstrom,　V=392.5(1)　angstrom(3),　D-c=9.37g.cm(-3),　lambda(MoKa)=0.71069　angstrom,　mu(MoKa)=514.43cm(-1)　and　F(000)=932.　The　final　R　is　0.051　for　706　observations.　TaNi2Te2　is　a　new　metal-rich　layered　ternary　telluride.　In　the　structure　trigonal　metal　sheets　are　sandwiched　below　and　above　by　Te　layers,　leading　to　planar　trigonal　coordination　for　Ta　and　trigonal　pyramidic　coordination　for　Ni　by　Te　atoms.　An　important　structural　character　of　this　compound　is　that　all　planar　five-member　TeNi4　rings　are　fused　together　to　form　an　extended　structure,　and　each　Ta　atom　is　sandwiched　by　two　TeNi4　rings.
