La2Re2Si2C crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 2-coordinate geometry to five equivalent Si(1) and two equivalent C(1) atoms. Re(1) is bonded in a single-bond geometry to three equivalent Si(1) and one C(1) atom. Si(1) is bonded in a 8-coordinate geometry to five equivalent La(1) and three equivalent Re(1) atoms. C(1) is bonded to four equivalent La(1) and two equivalent Re(1) atoms to form edge-sharing CLa4Re2 octahedra.
La2Re2Si2C crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 2-coordinate geometry to five equivalent Si(1) and two equivalent C(1) atoms. There is one shorter (3.18 Å) and four longer (3.25 Å) La(1)-Si(1) bond lengths. Both La(1)-C(1) bond lengths are 2.77 Å. Re(1) is bonded in a single-bond geometry to three equivalent Si(1) and one C(1) atom. There is one shorter (2.46 Å) and two longer (2.47 Å) Re(1)-Si(1) bond lengths. The Re(1)-C(1) bond length is 1.96 Å. Si(1) is bonded in a 8-coordinate geometry to five equivalent La(1) and three equivalent Re(1) atoms.
