Materials Data on SnO by Materials Project

Abstract

SnO crystallizes in the orthorhombic Cmc2_1 space group. The structure is two-dimensional and consists of two SnO sheets oriented in the (0, 0, 1) direction. there are two inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.18–2.43 Å. In the second Sn2+ site, Sn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.18–2.43 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four Sn2+ atoms to form a mixture of distorted corner and edge-sharing OSn4 tetrahedra. In the second O2- site, O2- is bonded to four Sn2+ atoms to form a mixture of distorted corner and edge-sharing OSn4 tetrahedra.
