In the first La3+ site, La3+ is bonded in a 5-coordinate geometry to two equivalent Os2- and three C+2.77- atoms. Both La–Os bond lengths are 3.26 Å. There are a spread of La–C bond distances ranging from 2.71–3.00 Å. In the second La3+ site, La3+ is bonded in a 4-coordinate geometry to two equivalent Os2- and two C+2.77- atoms. Both La–Os bond lengths are 3.24 Å. There are one shorter (2.83 Å) and one longer (2.85 Å) La–C bond lengths. In the third La3+ site, La3+ is bonded in a 4-coordinate geometry to two Os2- and two C+2.77- atoms. There are one shorter (3.22 Å) and one longer (3.24 Å) La–Os bond lengths. There are one shorter (2.85 Å) and one longer (2.86 Å) La–C bond lengths. In the fourth La3+ site, La3+ is bonded in a 5-coordinate geometry to two Os2- and three C+2.77- atoms.
