Abstract
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(II) perchlorate
with methanal, and alkylamines. The structure of
{3,10-bis(2-hydroxypropyl)-1,3,5,8,10,12-hexa-azacyclotetradecane}copper(II)
perchlorate is reported
[C14H34Cl2CuN6O10,

reflections]. The centrosymmetrical cation has a mean Cu–N distance
of 2·001(4) Å, with perchlorate ion oxygen atoms weakly
coordinated in the axial sites with a Cu–O distance of 2·61(1)
Å. 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(II) 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
