Materials Data on Cu(CO)4 by Materials Project

Abstract

Cu(CO)4 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of two Cu(CO)4 ribbons oriented in the (0, 0, 1) direction. Cu2+ is bonded to six O2- atoms to form edge-sharing CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.98–2.50 Å. There are two inequivalent C+1.50+ sites. In the first C+1.50+ site, C+1.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.26 Å. In the second C+1.50+ site, C+1.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.26 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu2+ and one C+1.50+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one C+1.50+ atom.
