Bis[3-methyl-5-(pyridin-2-yl)-1H-pyrazol-4-yl] selenide methanol hemisolvate.
The asymmetric unit of the title compound, C18H16N6Se·0.5CH3OH, contains two independent mol-ecules of bis-[3-methyl-5-(pyridin-2-yl)-1H-pyrazol-4-yl] selenide with similar C-Se-C bond angles [99.30 (14) and 98.26 (13)°], and a methanol molecule of solvation. In one mol-ecule, the dihedral angles between pyrazole and neighbouring pyridine rings are 18.3 (2) and 15.8 (2)°, and the corresponding angles in the other mol-ecule are 13.5 (2) and 8.3 (2)°. In the crystal, the selenide and solvent mol-ecules are linked by classical O-H⋯N and N-H⋯N hydrogen bonds, as well as by weak C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional supra-molecular architecture.
