Materials Data on TaP4(S2Cl)5 by Materials Project
TaCl5(P2S5)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two P2S5 clusters and one TaCl5 cluster. In each P2S5 cluster, there are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four S2- atoms to form corner-sharing PS4 tetrahedra. There are one shorter (1.92 Å) and three longer (2.12 Å) P–S bond lengths. In the second P5+ site, P5+ is bonded to four S2- atoms to form corner-sharing PS4 tetrahedra. There are one shorter (1.92 Å) and three longer (2.12 Å) P–S bond lengths. In the third P5+ site, P5+ is bonded to four S2- atoms to form corner-sharing PS4 tetrahedra. There are one shorter (1.92 Å) and three longer (2.12 Å) P–S bond lengths. In the fourth P5+ site, P5+ is bonded to four S2- atoms to form corner-sharing PS4 tetrahedra. There are one shorter (1.92 Å) and three longer (2.12 Å) P–S bond lengths. There are ten inequivalent S2- sites. In the first S2- site, S2- is bonded in a water-like geometry to two P5+ atoms. In the second S2- site, S2- is bonded in a single-bond geometry to one P5+ atom. In the third S2- site, S2- is bonded in a single-bond geometry to one P5+ atom. In the fourth S2- site, S2- is bonded in a single-bond geometry to one P5+ atom. In the fifth S2- site, S2- is bonded in a water-like geometry to two P5+ atoms. In the sixth S2- site, S2- is bonded in a water-like geometry to two P5+ atoms. In the seventh S2- site, S2- is bonded in a water-like geometry to two P5+ atoms. In the eighth S2- site, S2- is bonded in a water-like geometry to two P5+ atoms. In the ninth S2- site, S2- is bonded in a single-bond geometry to one P5+ atom. In the tenth S2- site, S2- is bonded in a water-like geometry to two P5+ atoms. In the TaCl5 cluster, Ta5+ is bonded to six Cl1- atoms to form edge-sharing TaCl6 octahedra. There are a spread of Ta–Cl bond distances ranging from 2.27–2.59 Å. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Ta5+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Ta5+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Ta5+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Ta5+ atom. In the fifth Cl1- site, Cl1- is bonded in a water-like geometry to two equivalent Ta5+ atoms.
