Compounds 2a and 2b react with FeCl2, CoCl2, RhCl3, NiCl2, CuBr2, and TmCl3 forming the complexes [FeCl(TAC)]Cl (3a), [FeCl(TBC)]Cl (3b), [CoCl(TAC)]Cl (4), [RhCl(TAC)]Cl2 (5), [NiCl(TAC)]Cl (6a), [NiCl(TBC)]Cl (6b), [CuBr(TAC)]Br (7), [TmCl(TAC)]Cl2 (8a), and [TmCl(TBC)]Cl2 (8b). The reaction of 6a with an excess of CuCl affords a coordination polymer in which [NiCl(TAC)]+ cations are connected by [Cu6Cl8]2− anions (9). The 1H and 13C 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.de540 Chemie und zugeordnete WissenschaftenTetraazacyclododecaneCobaltCopperIronNickelRhodiumThuliumcomplexesÜbergangsmetall- und Lanthanoid-Komplexe von 1,4,7,10-Tetraallylund 1,4,7,10-Tetra-3-butenyl-1,4,7,10-tetraazacyclododecanArticle1865-7117Transition Metal and Lanthanide Complexes of 1,4,7,10-Tetraallyl- and 1,4,7,10-Tetra-3-butenyl- 1,4,7,10-tetraazacyclododecane
