[2,6-Bis(6-methyl-quinolin-2-yl)pyridine-κN,N',N'']dichloridoiron(II).

In the mol-ecule of the title compound, [FeCl(2)(C(25)H(19)N(3))], the three N atoms span the axial-equatorial-axial sites of the trigonal-bipyramidal coordination polyhedron; the geometry of the Fe(II) atom is 32% distorted from trigonal-bipyramidal (towards square-pyramidal along the Berry pseudorotation pathway). One of the Cl atoms is disordered over two positions in a 0.938 (11):0.062 (11) ratio. Inter-molecular C-H⋯Cl hydrogen bonding occurs in the crystal structure.
