Crystal structure and supramolecular features of bis{ethyl 2-[1-methyl-3-(pyridin-2-yl)-1<i>H</i>-1,2,4-triazol-5-yl]acetate}trinitratolanthanum(III)
The title lanthanum(III) complex, [La(Et-MPTA)<sub>2</sub>(NO<sub>3</sub>)<sub>3</sub>] {where Et-MPTA is ethyl 2-[1-methyl-3-(pyridin-2-yl)-1<i>H</i>-1,2,4-triazol-5-yl]acetate} or [La(C<sub>24</sub>H<sub>28</sub>N<sub>8</sub>O<sub>4</sub>)(NO<sub>3</sub>)<sub>3</sub>], crystallizes in the monoclinic space group <i>C</i>2/<i>c</i> (No. 15). The lanthanum atom is twelve-coordinate, bonded to two oxygen atoms from carboxyl-ate groups, four nitro-gen atoms from two pyridinyl-1,2,4-triazole ligands, and six oxygen atoms of three NO<sub>3</sub> <sup>-</sup> anions. The coordination geometry around the lanthanum atom can be described as a distorted icosa-hedron. Supra-molecular features include π-stacking inter-actions between pyridyl and triazole rings and weak inter-molecular N-O⋯C inter-actions, which lead to the formation of layers parallel to the (101) plane.
