Materials Data on KBa4Au(CO)4 by Materials Project
KBa4Au(CO)4 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two KBa4Au(CO)4 sheets oriented in the (0, 0, 1) direction. K1+ is bonded in a square co-planar geometry to two equivalent C and four equivalent O2- atoms. Both K–C bond lengths are 2.97 Å. All K–O bond lengths are 2.36 Å. Ba2+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Ba–O bond lengths are 2.85 Å. Au1- is bonded in a square co-planar geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.00 Å. There are two inequivalent C sites. In the first C site, C is bonded in a linear geometry to one K1+ and one C atom. The C–C bond length is 1.27 Å. In the second C site, C is bonded in a single-bond geometry to one C atom. O2- is bonded to one K1+, four equivalent Ba2+, and one Au1- atom to form a mixture of distorted edge, face, and corner-sharing OKBa4Au octahedra. The corner-sharing octahedral tilt angles are 0°.
