The crystal structures of [6-nitro-12,14-dimethyl-3,9-bis(propylsulphonyl)-1,2,4,8,10,11-hexaazacyclotetra-deca-2,4,6,9,12, 14-hexaenato(2-)-N1, N4, N8, N11]nickel(II) and [12,14-dimethyl-3,9-bis(ethylsulphonyl)-1,2,4,8,10,11-hexaazacyclotetra-deca-2,4,6,9,12,14- hexaenato(2-)-N1, N4, N8, N11]nickel(II)
摘要:
Hexaazamocrocyclic complexes [6-nitro-12,14-dimethyl-3,9-bis(sulphonyl)-1,2,4,8,10,11-hexaazacyclotetra-deca-2,4,6,9,12,14-hexaenato(2-)-N-1,N-4,N-8,N-11]nickel(II) and [12,14-dimethyl-3,9-bis(ethylsulphonyl)-1,2,4,8,10,11-hexaazacyclotetra-deca-2,4,6,9,12,14-hexaenato(2-)-N-1,N-4,N-8,N-11]nickel(II) have been synthesized by a template procedure starting from an open-chain precursor. The crystal structure of both macrocycle products showed a square planar coordination geometry with cis-positioned-SR groups relative to the nickel atom.
