Abstract: In the title compound, [MnCl₂(C₁₆H₁₅N₅)(CH₄O)], the manganese(II) cation is six-coordinate, forming a distorted octahedral configuration with bis(1H-benzimidazol-2-ylmethyl)amine (IDB) serving as a neutral tridentate chelating ligand. Two imine and one amine N atoms from IDB and one Cl anion form the equatorial plane. The two axial positions are occupied by the methanol O atom and the other Cl anion. By a combination of two N-HCl and one O-HCl hydrogen bonds, molecules are linked into a three-dimensional network which is strengthened by weak C-H and - interactions [interplanar spacing = 3.343 (1) Å, ring-centroid separation = 3.728 (3) Å, corresponding to a ring offset of 1.650 (1) Å].
