Mercury 8-selenolquinolinate was synthesized and studied by X-ray diffraction. In neutral Hg(C9H6NSe)2, 8-selenolquinoline is a bidentate (S,N) ligand. The coordination polyhedron of mercury is a distorted tetrahedron or a seesaw (2Se + 2N). The bond lengths are as follows: Hg-Se, 2.4599(9) and 2.4606(9) Å; Hg...N, 2.497(6) and 2.513(6) Å. The SeHg...

The crystal-chemical properties of lanthanide oxobromotungstates of composition LnWO4Br(Ln = La, Pr, Nd, Sm) were studied: the crystal system and space group were determined, and the unit cell parameters were refined. The dependence of the unit cell parameters a, b, c, and V of the LnWO4Br compounds on the lanthanide atomic number was analyzed. The...

Methods were developed for manufacturing of isolated nanoparticles of lead(II) and mercury(II) oxides produced by the thermal decomposition of metal compounds in a solution-melt of low-density polyethylene (LDPE) in mineral oil. The PbO and HgO nanoparticles stabilized in the LDPE matrix were characterized using X-ray powder diffraction and transmi...
