2-(4-Fluoro-benzyl-idene)-N-(4-meth-oxy-benzylidene)-1,3,4-thia-diazol-2-amine.

ABSTRACT: The title compound, C(16)H(12)FN(3)OS, was synthesized by the reaction of 5-(4-meth-oxy-phen-yl)-1,3,4-thia-diazol-2-amine and 4-fluoro-benzaldehyde. An intra-molecular C-H⋯S hydrogen bond results in the formation of two five-membered rings. In the crystal structure, inter-molecular C-H⋯N hydrogen bonding links the mol-ecules, forming a two-dimensional network.
