By means of
alternating current electrochemical technique a new hybrid inorganic-organic π-complex [CuI4(Atu)2Cl4]∙2H2O∙2Ñ3H7OH
(1) (Atu = N-phenyl-N'-{3-allylsulfanyl-4-amino-5-phenyl-4H-1,2,4-triazol-4-yl}urea) has been
synthesized and characterized by X-ray single-crystal diffraction. Crystals of 1 are monoclinic, space group P21/c, a = 16.0745(10), b
= 18.0290(10), c = 8.9794(6) Å, β = 92.262(5)°, V = 2600.3(3) Å3
at 150 K, Z = 2. In the structure of 1, despite
the presence of the urea fragment, Atu acts a chelating-bridging
π,σ-ligand, connecting Cu(I) ions by means
of allylic C=C bonds and triazole N donor atoms, into {CuI2(Atu)2}2+
dimers. The latter are connected by anionic {Cu2Cl4}2–
subunits into infinite ladder-like chain. Not less interesting is the fact that
molecules of n-propanol and water are included in the crystal structure,
since both these molecules, through N—H···O hydrogen bonding with the urea
fragments of Atu, connect neighboring phenyl-urea substituents within
the same infinite chain.
