X-ray crystallographic studies on tetramethyl thiramdisulphide or bis (dimethyl thiocarbamoyl) disulphide

Rachna Tiwari, Jyotsna Chauhan, R.K.Tiwari

It has been observed that some of the fungicides are loosing their effects and becoming resistant to them. Analogous compounds can be designed as substitute, if their structures are known. A rational approach to test these fungicides is to know the three dimensional structure of these compounds and macromolecular receptor sites aswell as their molecular complex The structures of these compounds can be obtained by X-ray diffraction method in crystalline formand they will invariably be similar to their structure in solutions.The composition of Tetra methyl thiram disulphide or bis (dimethyl thiocarbamoyl) disulphide crystals are confirmed by comparing the infra-red spectra of the two components. The Unit cell parameters are a=6.91 30(10)Å,b=6.9250(10)Å c=11.8020(10)Å the space group is P1.
