This group of organochlorine insecticides is generally known as dieneorganochlorine insecticides or cyclodienes-cyclo means cyclic or ring structures and diene means containing two double bonds. They have three dimensional structures and exist as stereoisomers whose atoms differ in their spatiallocation and structure, with one and frequently two methanobridges, one located in the chlorinated ring (marked 2 in the diagram below) and the other in the unchlorinated ring (marked 1 in the diagram below).
