Abstract:A novel type of chalcogen bond between tellurium(II) and the carbon atom of the isocyanide groups has been discovered in five cocrystals: 1•TePy F 2 (two polymorphs), 2•TePy F 2 , 3•2TeTol F 2 , and 3• TePy F 2 . These were obtained by cocrystallization of monoisocyanide compounds CN-Np (Np-1 is 1-naphthyl; 1) and CNC 6 H 4 CCPh ( 2) and the bis-isocyanide 1,4-(CN) 2 C 6 Me 4 (3) with the chalcolanes TePy F 2 and TeTol F 2 (Py F = 4-NC 5 F 4 , Tol F = 4-CF 3 C 6 F 4 ). The structures were studied by X-ray diff… Show more
