LiInSiO4: a new monovalent-trivalent olivine.
The structure of the olivine LiInSiO(4) (lithium indium silicate) is isotypic with LiScSiO(4) and MgMgSiO(4) (forsterite). The main differences between the title compound and the divalent-divalent olivines are found for the bond lengths and angles opposite common edges between the tetrahedron and the Li(+) and In(3+) ion sites. The tetrahedron shares one common edge with the Li(+) site and two common edges with the In(3+) site. The tetrahedron is distinctly distorted, as are the Li(+) and In(3+) sites.
