Abstract

Co2(GeS)3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Co sites. In the first Co site, Co is bonded to two equivalent Ge and four S atoms to form CoGe2S4 octahedra that share corners with six CoGe2S4 octahedra and corners with four equivalent GeCo2S2 tetrahedra. The corner-sharing octahedra tilt angles range from 49–60°. Both Co–Ge bond lengths are 2.44 Å. There are two shorter (2.22 Å) and two longer (2.28 Å) Co–S bond lengths. In the second Co site, Co is bonded to four Ge and two equivalent S atoms to form CoGe4S2 octahedra that share corners with six CoGe2S4 octahedra and corners with four equivalent SCo2Ge2 tetrahedra. The corner-sharing octahedra tilt angles range from 49–63°. There are two shorter (2.32 Å) and two longer (2.38 Å) Co–Ge bond lengths. Both Co–S bond lengths are 2.17 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded to two equivalent Co and two equivalent S atoms to form GeCo2S2 tetrahedra that share corners with four equivalent CoGe2S4 octahedra, corners with two equivalent GeCo2S2 tetrahedra, and an edgeedge with one GeCo2S2 tetrahedra. The corner-sharing octahedra tilt angles range from 67–72°.more »« less
