Abstract

C crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four C clusters. there are seven inequivalent C sites. In the first C site, C is bonded in a trigonal planar geometry to three C atoms. There are a spread of C–C bond distances ranging from 1.37–1.54 Å. In the second C site, C is bonded in a bent 120 degrees geometry to two C atoms. There is one shorter (1.29 Å) and one longer (1.39 Å) C–C bond length. In the third C site, C is bonded in a bent 120 degrees geometry to two C atoms. The C–C bond length is 1.29 Å. In the fourth C site, C is bonded in a trigonal planar geometry to three C atoms. The C–C bond length is 1.40 Å. In the fifth C site, C is bonded in a bent 120 degrees geometry to two C atoms. The C–C bond length is 1.31 Å. In the sixth C site, C is bonded in a bent 120 degrees geometry to two equivalent C atoms. In the seventh C site, C is bonded in a bent 120 degrees geometry to two C atoms.
