X-Ray Crystallographic analysis of Fungicide monceren N-((4-chlorophenyl)methyl)-N-cyclopentyl-N'-phenylurea

Monceren N-((4-chlorophenyl)methyl)-N-cyclopentyl-N'-phenylurea, a local Non systemic fungicide with good protectant The activity of fungicides is intimately related to its chemical structure. Knowledge about the chemical structure of a chemical is useful for the synthesis of new compounds with more specific actions and fewer adverse reactions, to increase/decrease the duration of action of the original drug or to get a more potent compound, to restrict the action to a specific system of the body and to reduce the adverse reactions, toxicity and other disadvantages associated. We can understand the basic chemical groups responsible for fungicide action.Recently it has been observed that some of the fungicides are loosing their effects. If their structures are known. , analogous compounds can be designed as a substitute. .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 diffraction method in crystalline form and they will invariably be similar to their structure in solutions. The Monceren N-((4-chlorophenyl)methyl)-Ncyclopentyl-N'-phenylurea molecular structures obtain by the XRay Diffraction method in crystalline form. Crystal size of monceren is nearly 0.46 x 0.120 x 0.060 mm. We determine the threedimensional structure, molecular dimensional, molecular geometry, electronic structure and the conformation of fungicides and analyze their crystal structures also. The composition of crystal Monceren N-((4chlorophenyl)methyl)-N-cyclopentyl-N'-phenylurea is confirmed by comparing the infra-red spectra The unit cell parameters are a = 12.1887(12)) Å b = 8.7677(8) Å ,c = 33.063Å α = 90 o , β = 90.00 , γ = 90 o The Crystal system is Orthorhombic.
