STRUCTURAL STUDY OF A NEW 1-(2-THIENYL)-3-(3-METHYL-2-THIENYL)-PROPENONE, IN SITU RADIATION-INDUCED DIMERIZATION PRODUCTS

The new conjugated system ("chalcone kind") reported herein, 1-(2-thienyl)-3-(3-methyl-2-thienyl)-propenone, C12H10OS2 presents a monomeric molecular structure, and it most interesting aspects are to be found in it intermolecular interactions, of varied type (C-H-O, C-H---7C, n-n) and stre...
