Materials Data on Cu3As4 by Materials Project
Cu3As4 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Cu3As4 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Cu+1.33+ sites. In the first Cu+1.33+ site, Cu+1.33+ is bonded in a 4-coordinate geometry to four As1- atoms. There are two shorter (2.44 Å) and two longer (2.51 Å) Cu–As bond lengths. In the second Cu+1.33+ site, Cu+1.33+ is bonded in a 6-coordinate geometry to six As1- atoms. There are two shorter (2.45 Å) and four longer (2.52 Å) Cu–As bond lengths. There are three inequivalent As1- sites. In the first As1- site, As1- is bonded in a 4-coordinate geometry to four Cu+1.33+ atoms. In the second As1- site, As1- is bonded in a 4-coordinate geometry to four equivalent Cu+1.33+ atoms. In the third As1- site, As1- is bonded in a distorted L-shaped geometry to two equivalent Cu+1.33+ atoms.
