Tm2C(NO)2 crystallizes in the trigonal P-3m1 space group. Tm(1) is bonded in a 7-coordinate geometry to three equivalent N(1) and four equivalent O(1) atoms. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Tm(1) and one C(1) atom. O(1) is bonded to four equivalent Tm(1) atoms to form a mixture of edge and corner-sharing OTm4 tetrahedra.
Tm2C(NO)2 crystallizes in the trigonal P-3m1 space group. Tm(1) is bonded in a 7-coordinate geometry to three equivalent N(1) and four equivalent O(1) atoms. All Tm(1)-N(1) bond lengths are 2.54 Å. There are three shorter (2.20 Å) and one longer (2.27 Å) Tm(1)-O(1) bond length. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both C(1)-N(1) bond lengths are 1.24 Å. N(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Tm(1) and one C(1) atom. O(1) is bonded to four equivalent Tm(1) atoms to form a mixture of edge and corner-sharing OTm4 tetrahedra.
