Crystal structure of bis­{3-(3-bromo-4-methoxyphenyl)-5-[6-(1H-pyrazol-1-yl)pyridin-2-yl]-1,2,4-triazol-3-ato}­iron(II) methano­l disolvate

The unit cell of the title compound, [FeII(C17H12BrN6O)2]·2MeOH, consists of a charge-neutral complex mol­ecule and two independent mol­ecules of methanol. In the complex mol­ecule, the two tridentate ligand mol­ecules 2-[5-(3-bromo-4-meth­oxy­phen­yl)-4H-1,2,4-triazol-3-yl]-6-(1H-pyrazol-1-yl)pyridine coordinate to the FeII ion through the N atoms of the pyrazole, pyridine and triazole groups, forming a pseudo-octa­hedral coordination sphere around the central ion. In the crystal, neighbouring asymmetric mol­ecules are linked through weak C—H(pz)⋯π(ph) inter­actions into chains, which are then linked into layers by weak C–H⋯N/C inter­actions. Finally, the layers stack into a three-dimensional network linked by weak inter­layer C—H⋯π inter­actions between the meth­oxy groups and the phenyl rings. The inter­molecular contacts were qu­anti­fied using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing the relative contributions of the contacts to the crystal packing to be H⋯H 34.2%, H⋯C/C⋯H 25.2%, H⋯Br/Br⋯H 13.2%, H⋯N/N⋯H 12.2% and H⋯O/O⋯H 4.0%. The average Fe—N bond distance is 1.949 Å, indicating the low-spin state of the FeII ion. Energy framework analysis at the HF/3–21 G theory level was performed to qu­antify the inter­action energies in the crystal structure.
