inorganic compounds
The title compound has been synthesized by a solid-state reaction. Its structure is isotypic with those of LiMgBO3, LiMnBO3 and LiZnBO3. CoII 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.
