Abstract
The crystal structure of [Cu(Him)2(CO3)]·H2O, determined from conventional X-ray powder diffraction methods, allowed to clarify, on the basis of a structural interpretation of the chemical transformation, the role of the title compound in the formation of the blue phase of Cu(im)2 [Cu(Him)2(CO3)]·H2O is triclinic, P1̅; a = 8.8565(7), b = 8.9579(5), c = 8.3705(6) Å, α = 105.728(4)°, β = 105.318(3)°, γ = 114.369(4)°; final Rwp, Rp and RF agreement factors, for 4700 data collected in the 11–105° range, are 0.053, 0.036 and 0.078, respectively.
