Carbonato(1,4,7,10-tetraazacyclododecane)cobalt(III) perchlorate monohydrate

Utilization of IR spectral detailed analysis for coordination mode determination in novel Zn–cyclen–aminoacid complexes

“…The central atom, N1 and O2 atoms are located at twofold rotation axis (special position with side symmetry 2f). Similar coordination mode was observed in [Ni(cyclen)( 2 -CH 3 COO)]BF 4 [47], [Ni 2 (cyclen) 2 (-tp)]ClO 4 (tp -terephthalate dianion) [48] and [Co(cyclen)CO 3 ]ClO 4 [49] complexes. The Zn-N(cyclen) distances are longer than the average M-N length (2.…”

Nitrato(1,4,7,10-tetraazacyclododecane)copper(II) nitrate

“…No trans-octahedral MLX 2 complexes are known, although there is evidence for square-planar Ni II complexes in solutions containing large amounts of inert electrolyte at high temperature (Fabbrizzi, 1977). Folded cis-octahedral complexes are known for Co n (Loehlin & Fleischer, 1976;Iitaka, Shina & Kimura, 1974) and suggested for Ni H (Smierciak, Passariello & Blinn, 1977). For CuLX 2 (X = CI, NOa) spectral and other evidence suggest five-coordination (Styka, Smierciak, Blinn, DeSimone & Passariello, 1978) and the enthalpy of formation of CuLE+(aq.)…”
