ChemInform Abstract: DETERMINATION OF LATTICE CONSTANTS AND SPACE GROUPS FOR CRYSTALS OF TETRAUREA ADDUCTS WITH MN(++), CO(++), NI(++), AND ZN(++) NITRATES

Bis[1,3-dimethyl-3,4,5,6-tetrahydropyrimidin-2(1H)-one-κO]diiodocadmium(II)

“…This is only the second molecular CdI 2 O 2 complex reported to date. No geometrical comparisons with the previously reported complex, bis(urea)diiodocadmium(II) (Durski et al, 1975) could be made as no coordinates are available in the Cambridge Structural Database (Version of November 2005;Allen, 2002) for the urea complex. The molecular structure of (I), showing 50% probability displacement ellipsoids (arbitrary spheres for the H atoms).…”

Preparation of cadmium sulfide from CdCl2(CdBr2, CdI2)-CS(NH2)2-CH3OH systems

“…The increase in the thiourea concentration leads to an increase in the solubility of CdBr 2 in the field of equilibrium existence of the crystalline solvate CdBr 2" 3CH3OH present in the binary system CdBr2-CH3OH [17]. The fields of equilibrium coexistence of the double salts CdBr2.CS(NH2) 2 and CdBr2"2CS(NH2)2 [19] are characterized by a complicated complexation due to a salting-out process and a subsequent enhancement of the CdBr 2 solubility. The double salt CdBr2"2CS(NH2) 2 is congruently soluble and can be obtained from the solution by isothermal evaporation of the methanol.…”
