It has been observed that some of these 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 as well as their molecular complex The structures of these compounds can be obtained by X-ray diffractionmethod in crystalline formand theywill invariably be similar to their structure in solutions. The composition of 3, 5-dimethyl 1,3,5- thiadiazine-2-thione crystals are confirmed by comparing the infra-red spectra of the two components. TheUnit cell parameters are a=6.4270(10)Å, b=6.4270(10)Å, c=32.8890(10) Å and Z=6. Thus the space group is determined to be P61 and crystal of hexagonal system.
