Abstract: Nd10B9C12 crystallizes in the tetragonal P4_12_12 space group. The structure is three-dimensional. there are five inequivalent Nd+2.70+ sites. In the first Nd+2.70+ site, Nd+2.70+ is bonded in a distorted hexagonal planar geometry to six C4- atoms. There are a spread of Nd–C bond distances ranging from 2.56–2.97 Å. In the second Nd+2.70+ site, Nd+2.70+ is bonded in a 6-coordinate geometry to six C4- atoms. There are a spread of Nd–C bond distances ranging from 2.61–3.04 Å. In the third Nd+2.70+ site, Nd+2.70+ is bonded in a distorted ...
