Sr Sr Ca Cd
Sr2CaCd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2CaCd cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Ca(1) and one Cd(1) atom. The Sr(1)-Ca(1) bond length is 2.68 Å. The Sr(1)-Cd(1) bond length is 1.47 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Cd(1) atom. The Sr(2)-Cd(1) bond length is 1.55 Å. Ca(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. Cd(1) is bonded in a bent 120 degrees geometry to one Sr(1) and one Sr(2) atom.
