Abstract
K3Cr2P3S12 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to six S2- atoms. There are a spread of K–S bond distances ranging from 3.28–3.70 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of K–S bond distances ranging from 3.20–3.59 Å. In the third K1+ site, K1+ is bonded in a distorted hexagonal planar geometry to six S2- atoms. There are a spread of K–S bond distances ranging from 3.24–3.47 Å. There are two inequivalent Cr3+ sites. In the first Cr3+ site, Cr3+ is bonded to six S2- atoms to form CrS6 octahedra that share an edgeedge with one CrS6 octahedra and edges with three PS4 tetrahedra. There are a spread of Cr–S bond distances ranging from 2.40–2.48 Å. In the second Cr3+ site, Cr3+ is bonded to six S2- atoms to form CrS6 octahedra that share an edgeedge with one CrS6 octahedra and edges with three PS4 tetrahedra. There are a spread of Cr–S bond distances ranging from 2.39–2.49 Å. There are three inequivalent P5+ sites.more »

In the first P5+ site, P5+ is bonded to four S2- atoms to form PS4 tetrahedra that share edges with two CrS6 octahedra. There are a spread of P–S bond distances ranging from 1.99–2.12 Å.
