Copper(II) compounds of 5-alkyl-3,5,7-triazanonane-1,9-diamines and 3,10-bisalkyl-1,3,5,8,10,12-hexaazacyclotetradecanes;: the structure of 1R,5S,8R,12S-{3,10-Bis(2-hydroxypropyl)-1,3,5,8,10,12-hexaazacyclotetradecane-N1,N5, N8,N12}copper(II) perchlorate

Preparations are reported for (3,10-bisalkyl-1,3,5,8,10,12-hexaazacyclotetradecane)copper(II) perchlorates (alkyl=propyl, 1-methylethyl, butyl, cyclohexyl, 2-(diethylammmonio)ethyl, 2-hydroxyethyl, 3-hydroxypropyl and 2-hydroxypropyl) by reaction of bis(ethane-1,2-diamine)copper(Ir) perchlorate with methanal, and alkylamines. The structure of {3,10-bis(2-hydroxypropyl)-1,3,5,8,10,12-hexaazacyclotetradecane}copper(II) perchlorate is reported [C14H34C12CuN6O10, monoclinic, space group P2(1)/c, a 8.504(2), b 14.855(5), c 9.034(2) Angstrom, beta 98.99(2)degrees, Z 2, R-1 0.061 for 1667 reflections]. The centrosymmetrical cation has a mean Cu-N distance of 2.001(4) Angstrom, with perchlorate ion oxygen atoms weakly coordinated in the axial sites with a Cu-O distance of 2.61(1) Angstrom. The planar copper(II) macrocycle cations form stacks which are linked by N-H ... O and O-H ... O-ClO3 hydrogen bonds involving the extended 2-hydroxypropyl substituents, with no interaction between the copper(II) ion and the hydroxy groups. (5-Alkyl-3,5,7-triazanonane-1,9-diamine) copper(ll) perchlorate compounds with the same 3-substituent alkyl groups (plus methyl, and ethyl, and also phenyl) are similarly prepared by using 1 mole proportion of the amine and 2 mole proportions of methanal.
