Bis(methanol-κO)bis{5-(pyridin-2-yl-κN)-3-[4-(pyridin-4-yl)phenyl]-1H-1,2,4-triazol-1-ido-κN1}cobalt(II)

Abstract

The asymmetric unit of the title CoII complex, [Co(C18H12N5)2(CH3OH)2], contains one half-molecule, and the complex is completed by application of an inversion centre. The CoII cation is coordinated by two deprotonated 1,2,4-triazole-based ligands, and two methanol molecules, in an N4O2 octahedral coordination geometry. Four N atoms are placed in the equatorial plane, while trans-methanol molecules occupy the axial positions. In the crystal, neighbouring complexes are linked via O—H...N hydrogen-bonding interactions, involving the methanol as donor and non-coordinating N triazole sites as acceptor groups, forming a two-dimensional network parallel to (100).
