Ca Bi Bi P
CaBi2P crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaBi2P clusters. Ca(1) is bonded in a distorted single-bond geometry to one Bi(1) and one P(1) atom. The Ca(1)-Bi(1) bond length is 2.47 Å. The Ca(1)-P(1) bond length is 1.39 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Ca(1) atom. In the second Bi site, Bi(2) is bonded in a single-bond geometry to one P(1) atom. The Bi(2)-P(1) bond length is 2.15 Å. P(1) is bonded in a distorted single-bond geometry to one Ca(1) and one Bi(2) atom.
