1,4,7,10-Tetraazacyclododecane (1) reacts with allylbromide and 3-butenylbromide giving 1,4,7,10-tetraallyl-1,4,7,10-tetraazacyclododecane (TAC) (2a) and 1,4,7,10-tetra-3-butenyl-1,4,7,10- tetraazacyclododecane (TBC) (2b), respectively. Compounds 2a and 2b react with FeCl 2 , CoCl 2 , RhCl 3 , NiCl 2 , CuBr 2 , and TmCl 3  forming the complexes [FeCl(TAC)]Cl (3a), [FeCl(TBC)]Cl (3b), [CoCl(TAC)]Cl (4), [RhCl(TAC)]Cl 2  (5), [NiCl(TAC)]Cl (6a), [NiCl(TBC)]Cl (6b), [CuBr(TAC)]Br (7), [TmCl(TAC)]Cl 2  (8a), and [TmCl(TBC)]Cl 2  (8b). The reaction of 6a with an excess of CuCl affords a coordination polymer in which [NiCl(TAC)] +  cations are connected by [Cu 6 Cl 8 ] 2 −   anions (9). The  1 H and  13 C NMR spectra of 2a, 2b, 5, and 6a, as well as the single crystal X-ray structures of 2a  ・ 3HCl, 6a, 6b, 7, and 9 are reported and discussed.
