Sr Sr Sn P
Sr2SnP crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and two equivalent P(1) atoms. The Sr(1)-Sn(1) bond length is 2.61 Å. There is one shorter (2.29 Å) and one longer (3.62 Å) Sr(1)-P(1) bond length. In the second Sr site, Sr(2) is bonded in a distorted single-bond geometry to one Sn(1) and two equivalent P(1) atoms. The Sr(2)-Sn(1) bond length is 1.58 Å. There is one shorter (2.75 Å) and one longer (2.96 Å) Sr(2)-P(1) bond length. Sn(1) is bonded in a distorted single-bond geometry to one Sr(1), one Sr(2), and two equivalent P(1) atoms. There is one shorter (2.84 Å) and one longer (2.95 Å) Sn(1)-P(1) bond length. P(1) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Sn(1) atoms.
