Materials Data on VCo3 by Materials Project

Abstract

Co3V crystallizes in the hexagonal P6/mmm space group. The structure is two-dimensional and consists of one Co3V sheet oriented in the (0, 0, 1) direction. there are two inequivalent V sites. In the first V site, V is bonded to one V and six Co atoms to form distorted corner-sharing VVCo6 hexagonal pyramids. The V–V bond length is 2.53 Å. There are three shorter (2.28 Å) and three longer (2.40 Å) V–Co bond lengths. In the second V site, V is bonded in a distorted hexagonal planar geometry to six equivalent Co atoms. All V–Co bond lengths are 2.43 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 2-coordinate geometry to two equivalent V and four equivalent Co atoms. All Co–Co bond lengths are 2.44 Å. In the second Co site, Co is bonded in a 7-coordinate geometry to two V and five Co atoms. There are one shorter (2.27 Å) and two longer (2.31 Å) Co–Co bond lengths.
