Crystal structure of [(E)-({2-[3-(2-{(1E)-[(carbamo­thioyl­amino)­imino]­meth­yl}phen­oxy)prop­oxy]phen­yl}methyl­idene)amino]­thio­urea with an unknown solvate

The title mol­ecule, C(19)H(22)N(6)O(2)S(2), has crystallographically imposed C (2) symmetry, with the central C atom lying on the rotation axis. The O—C—C—C torsion angle for the central chain is −59.22 (16)° and the dihedral angle between the planes of the benzene rings is 75.20 (7)°. In the crystal, N—H⋯O and N—H⋯S inter­actions link the mol­ecules, forming a three-dimensional network encompassing channels running parallel to the c axis, which account for about 20% of the unit-cell volume. The contribution to the scattering from the highly disordered solvent mol­ecules in these channels was removed with the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18] in PLATON. The stated crystal data for M (r), μ etc. do not take these into account.
