  • Synthesis and structure of diaquadichlorobis {9-[(2-hydroxyetoxy)methyl]guanine} coppe(II)
    Blažič, Boris, 1961- ...
    A compound with the title ▫$[Cu(C_8 H_11 N_5 O_3)_2 (H_2 O)_2]$▫ has been prepared from an aqueous solution of ▫$CuCl_2$▫ and 9-[(hydroxyethoxy)methyl]guanine, acyclovir. The crystal structure has ... been determinated by x-ray diffraction. The compound crystallizes in the monoclinicspace group C2/c with a=19,416(2), b=10.0861(1), c=13,524(2) Å, ▫$\beta=111.17(1)°, V=2469.67 Å^3$▫, Z=4. Least-squares refinement of the structure based on 1775 observations led to an R factor of 0.038. The structure consists of distored octahedral molecules with Cl ligands and ▫$H_2 O$▫ ligands in trans positions [Cu-Cl 2.883(1) and Cu-O(W) 1.983(2) Å]. The [(2-hydroxyethoxy)methyl]guanine is trans linked to Cu through N(7) [2.029(2) Å]. The side chain is partially folded. A short intramolecular hydrogen bond between O(0) and O(W1)[2.594 Å] significantly lowers the carbonyl stretching frequency [1715 to 1657 ▫$cm^{-1}$▫] in the FT-IR spectrum.
