Sr Se Se Cl
SrSe2Cl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrSe2Cl cluster. Sr(1) is bonded in a distorted bent 150 degrees geometry to one Se(2) and one Cl(1) atom. The Sr(1)-Se(2) bond length is 1.70 Å. The Sr(1)-Cl(1) bond length is 1.29 Å. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a single-bond geometry to one Cl(1) atom. The Se(1)-Cl(1) bond length is 0.65 Å. In the second Se site, Se(2) is bonded in a distorted single-bond geometry to one Sr(1) atom. Cl(1) is bonded in a bent 120 degrees geometry to one Sr(1) and one Se(1) atom.
