Y2C(NO)2 crystallizes in the trigonal P-3m1 space group. Y(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 4-coordinate geometry to three equivalent Y(1) and one C(1) atom. O(1) is bonded to four equivalent Y(1) atoms to form a mixture of edge and corner-sharing OY4 tetrahedra.
Y2C(NO)2 crystallizes in the trigonal P-3m1 space group. Y(1) is bonded in a 7-coordinate geometry to three equivalent N(1) and four equivalent O(1) atoms. All Y(1)-N(1) bond lengths are 2.56 Å. There are three shorter (2.22 Å) and one longer (2.29 Å) Y(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 1.23 Å. N(1) is bonded in a 4-coordinate geometry to three equivalent Y(1) and one C(1) atom. O(1) is bonded to four equivalent Y(1) atoms to form a mixture of edge and corner-sharing OY4 tetrahedra.
