The incorporation of benzodithiazolyl (BDTA) and methylbenzodithiazolyl (MBDTA) radicals into porous hybrid frameworks via gas phase diffusion revealed that inclusion appeared selective for the MIL53(Al) framework against a range of other potential hosts. Both PXRD and EPR studies are consistent with retention of a π*-π* dimer motif for BDTA in MIL53(Al)@BDTA whereas MBDTA in MIL53(Al)@MBDTA appears to be monomeric. The guests are readily released by the addition of solvent (CH(2)Cl(2)).

The title compound, C(16)H(18)N(4)S(2), was prepared by the substitution reaction of two equivalents of 2-mercaptoimidazole for every bromine substituent of 1,4-bis-(bromo-meth-yl)-2,5-dimethyl-benzene. The mol-ecule is located on a crystallographic centre of inversion and therefore adopts a trans configuration with regards to the orientation of the two sulfur atoms. An inter-molecular N-H⋯N hydrogen bond forms layers of mol-ecules parallel to (03).

In the crystal structure, mol-ecules are linked by weak C-H⋯O hydrogen bonds to form chains that pack in layers in a herringbone fashion.
