There are a spread of Ta–S bond distances ranging from 2.45–2.54 Å. In the second Ta+3.33+ site, Ta+3.33+ is bonded to six S2- atoms to form distorted TaS6 pentagonal pyramids that share corners with seven CuS4 trigonal pyramids and edges with six TaS6 pentagonal pyramids. There are a spread of Ta–S bond distances ranging from 2.47–2.50 Å. In the third Ta+3.33+ site, Ta+3.33+ is bonded to six S2- atoms to form distorted TaS6 pentagonal pyramids that share corners with five CuS4 trigonal pyramids, edges with six TaS6 pentagonal pyramids, and a faceface with one CuS4 trigonal pyramid.
