Abstract

La2Ta3S2O8 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 9-coordinate geometry to two S2- and seven O2- atoms. There are one shorter (3.06 Å) and one longer (3.10 Å) La–S bond lengths. There are a spread of La–O bond distances ranging from 2.47–2.69 Å. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to two S2- and seven O2- atoms. There are one shorter (2.89 Å) and one longer (3.11 Å) La–S bond lengths. There are a spread of La–O bond distances ranging from 2.48–2.66 Å. There are two inequivalent Ta+4.67+ sites. In the first Ta+4.67+ site, Ta+4.67+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ta–O bond distances ranging from 1.86–2.33 Å. In the second Ta+4.67+ site, Ta+4.67+ is bonded in a 6-coordinate geometry to four S2- and two equivalent O2- atoms. There are two shorter (2.46 Å) and two longer (2.72 Å) Ta–S bond lengths. Both Ta–O bond lengths are 1.99 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinatemore »« less
