Cobalt Lithium Orthoborate, LiCoBO₃

The title compound has been synthesized by a solid-state reaction. Its structure is isotypic with those of LiMgBO₃, LiMnBO₃ and LiZnBO₃. Co^II occupies statistically two close positions within the CoO₅ trigonal bipyramids. These polyhedra share edges to form chains running along the [01] axis and are linked together, via corner sharing, by BO₃ planar groups. The Li atoms occupy statistically the center of two face-sharing tetrahedra. Such pairs of tetrahedra share edges to form chains running along the c axis.
