Structure-Property-Relationship of p-Toluidinium Tetrachloromercurate(II)

The single crystals of p-toluidinium tetrachloromercurate(II) hybrid materials have been grown with perfect crystal of size 0.35 x 0.30 x 0.27 mm. The hybrid material is exposed to X-rays for 3D intensity data which is used to refine the crystal structure upto reliability-factor of 0.034. The phenyl ring has planar conformation with skeletal torsion angle of 0.003(6)degrees and the aromatic ring (C1-C6) forms an angle of 78.7(1)degrees to the plane of inorganic layer. The N-H center dot center dot center dot Cl hydrogen bonded tetramer pattern is observed in p-toluidinium tetrachloromercurate(II) and the two tetramer layers are separated by a distance of 3.925(6)angstrom and the minimum distance between two mercury atoms is 4.112(1)angstrom which is quite larger for any metallophilic interaction. The inorganic layers form zig-zag ribbons which are separated by a distance of 12.987(5)angstrom.
