An x-ray diffraction structural study was carried out on dicyanoglyoxime trihydrate (DCG) and dimesitylglyoxime (DMG) on an automatic diffractometer using λMoKα radiation using 851 reflections, R=0.031 (DCG) and 862 reflections, R=0.030 (DMG). The unit cell parameters of the monoclinic crystals of DCG, C4H2N4O2·3H2O at −155°C are as follows: a=17.34(1), b=8.395(6), c=6.280(5) Å, β=97.23(6)°, Z=4, space group C2/c. The unit cell parameters of the monoclinic crystals of DMG, C20H24N2O2 at 23°C are as follows: a=12.734(2), b=8.885(2), c=16.087(2) Å, β=101.31(1)°, Z=4, space group I2/a. DCG and DMG molecules in the crystal have anti form with anti-peri-planar orientation of the oxime groups. The planar dioxime fragments features π-conjugation of the oxime groups. The molecules in the crystal are connected by hydrogen bonds, which form a three-dimensional framework in the structure of DCG and chains along the a-axis in the structure of DMG.

AbstractAn x-ray diffraction structural investigation was carried out on amphi-phenylglyoxime (PGO) and amphi-chloroglyoxime (CGO), which crystallizes as a monohydrate, on a diffractometer using λMoKα radiation. The structure of PGO was solved by the direct method using 745 reflections, R=0.029. The structure of CGO was solved using the direct method using 1397 reflections, R=0.031. The unit cell parameters of the triclinic crystals of PGO, C8H8N2O2, at 23°C are as follows: a=3.966(1), b=8.624(2), c=11.792(2) Å, α=91.04(3), β=97.17(3), γ=95.52(2)°, Z=2, space group P
