Materials Data on Sr2Zn3Cd by Materials Project

Sr2CdZn3 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 12-coordinate geometry to three equivalent Cd and nine Zn atoms. There are one shorter (3.42 Å) and two longer (3.58 Å) Sr–Cd bond lengths. There are a spread of Sr–Zn bond distances ranging from 3.29–3.56 Å. In the second Sr site, Sr is bonded in a 12-coordinate geometry to three equivalent Cd and nine Zn atoms. There are two shorter (3.34 Å) and one longer (3.37 Å) Sr–Cd bond lengths. There are a spread of Sr–Zn bond distances ranging from 3.30–3.64 Å. Cd is bonded in a 10-coordinate geometry to six Sr and four Zn atoms. There are a spread of Cd–Zn bond distances ranging from 2.85–3.00 Å. There are three inequivalent Zn sites. In the first Zn site, Zn is bonded in a 10-coordinate geometry to six Sr, one Cd, and three Zn atoms. There are two shorter (2.77 Å) and one longer (2.90 Å) Zn–Zn bond lengths. In the second Zn site, Zn is bonded in a 10-coordinate geometry to six Sr, two equivalent Cd, and two Zn atoms. The Zn–Zn bond length is 2.72 Å. In the third Zn site, Zn is bonded in a 10-coordinate geometry to six Sr, one Cd, and three Zn atoms.
