The use of molecular layer notation t-o-f for the identification of MX2 polytypes is presented. An application of different symbolic notations of MX2 crystals for the polytypic structure analysis is discussed. The structures of 13 new polytypes of Cdl2, have been determined: 10H3 : f2f1f2of1 ; 10H4 : tf2(o)2f1 ; 10H5 : tf4tf2f2 ; 12H8 : f2f1f2(o)2f1 ; 12H9 : tf2(o)3f1 ; 20H14 : (t)7f5tf4 ; 24H10 : (t)7f2f1(t)3f2(o)2f1 ; 42H2 : (t)4f2f1(t)3f2of1(t)3(f2of1)2 ; 30R3 : tf5f4f2f1 ; 30R4 : f2of2f1f1 ; 42R2 : (t)2f4tf2f1f5 ; 54R4 : (t)4f5(t)2f1f1 ; 78R2 : (t)8f5(t)2f1f1.
