2,2'-(Disulfanedi-yl)dibenzoic acid-N,N'-bis-(4-pyridyl-meth-yl)ethane-dithio-amide (1/1).

ABSTRACT: The asymmetric unit of the title co-crystal, C(14)H(14)N(4)S(2)·C(14)H(10)O(4)S(2), comprises a twisted 2,2'-(disulfanedi-yl)dibenzoic acid mol-ecule [dihedral angle between the benzene rings = 83.53?(14)°] and a U-shaped mol-ecule of N,N'-bis-(4-pyridyl-meth-yl)ethane-dithio-amide in which intra-molecular N-H?S hydrogen bonds are observed. Two mol-ecules of each form a centrosymmetric ring, with an extended chair conformation, mediated by carbox-yl-pyridine O-H?N hydrogen bonds between the carboxylic acid groups of two 2,2'-(disulfanediyl)dibenzoic acid molecules and pyridine-N atoms of two N,N'-bis(4-pyridylmethyl)ethanedithioamide molecules. The tetra-meric aggregates are linked into a supra-molecular chain along the b axis via amide-carbonyl N-H?O hydrogen bonds.
