Crystal structure of 3,3′-diisopropyl-1,1′-(pyridine-2,6-di­yl)bis­[1H-imidazole-2(3H)-thione]

In the title compound, C(17)H(21)N(5)S(2), the dihedral angles between the central pyridine ring and its pendant imidazole rings are 29.40 (9) and 40.77 (9)°; the pendant rings are twisted in an opposite sense with respect to the central ring. In each case, the S atom is approximately anti to the N atom of the pyridine ring. For both substituents, the H atom attached to the central C atom of the isopropyl group is approximately syn to the S atom in the attached ring. In the crystal, mol­ecules are linked by weak C—H⋯S inter­actions, generating C(5) chains propagating along [001].
