A new crystalline [CuI2(DIMPA)4(ClO4)2]
complex has been obtained by the alternating-current electrochemical technique
from a water-ethanol solution of 3,5-dimethyl-1H-pyrazole
(DIMPA) and
Cu(ClO4)2, and its crystal has been studied by
single-crystal X-ray diffraction. The crystal structure is monoclinic, space
group P21/n,
Z = 4, a = 13.834(3), b = 10.170(3),
c = 20.610(5) Å, β = 96.13(3)°, V = 2883.1(13) Å3
(at 100 K). The two independent Cu(I) atoms adopt
different coordination environments, formed by two N atoms of two neighboring DIMPA molecules
and one or two O atoms of a ClO4– anion. To analyze the
hydrogen bonding pattern in the structure, a Hirshfeld
surface analysis was performed.
