LaCoN3 crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 5-coordinate geometry to two equivalent N(3) and three equivalent N(1) atoms. Co(1) is bonded in a distorted trigonal planar geometry to one N(2) and two equivalent N(1) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent La(1) and two equivalent Co(1) atoms to form a mixture of edge and corner-sharing NLa3Co2 trigonal bipyramids. In the second N site, N(2) is bonded in a 1-coordinate geometry to one Co(1) and one N(3) atom. In the third N site, N(3) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one N(2) atom.
LaCoN3 crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 5-coordinate geometry to two equivalent N(3) and three equivalent N(1) atoms. Both La(1)-N(3) bond lengths are 2.77 Å. There is one shorter (2.42 Å) and two longer (2.46 Å) La(1)-N(1) bond lengths. Co(1) is bonded in a distorted trigonal planar geometry to one N(2) and two equivalent N(1) atoms. The Co(1)-N(2) bond length is 1.66 Å. There is one shorter (1.84 Å) and one longer (1.90 Å) Co(1)-N(1) bond length. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent La(1) and two equivalent Co(1) atoms to form a mixture of edge and corner-sharing NLa3Co2 trigonal bipyramids. In the second N site, N(2) is bonded in a 1-coordinate geometry to one Co(1) and one N(3) atom. The N(2)-N(3) bond length is 1.18 Å. In the third N site, N(3) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one N(2) atom.
