The two non-isostructural lanthanum pnictogenide selenides La3NSe3 and La3PSe3 are formed by oxidizing metal with sodium azide (NaN3) in the presence of selenium an excess iodine for eight days at 850 °C reacting binary compounds sesquiselenide (La2Se3) monophosphide (LaP) four 900 torch-sealed glassy silica ampoules. crystallizes well-known Sm3NS3-type structure orthorhombic space group Pnma l...

Monolayer molybdenum trioxide (MoO$_3$) is an emerging two-dimensional (2D) material with high electrical conductivity. Using first-principles calculations and a Boltzmann transport theoretical framework, we predict record low room-temperature phonon thermal conductivity ($\kappa_p$) of 1.57 W/mK 1.26 along the principal in-plane directions MoO$_3$ monolayer. The behavior attributed to combinat...

Copper complexes of [Cu(phen)(tda)].2H2O(1) and [(phen)2Cu(µ-tda) Cu(phen)](ClO4)2.1.5H2O (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. Both complexes were characterized by elemental analysis, IR, UV–Vis spectroscopy and cyclic voltammetry. Their solid state struct...

A series of complexes of the type trans-[Co(acacen)(amine)2]ClO4, where (acacen) is the (bis(acetyleacetone) ethylenediimine) and the amines are Benzyl amine (bzlan) 1, 2-amino pyrimidine (2ampy) 2, N-methylpipirazine (nmpip) 3, 3-methyl pyridine (3mpy) 4, p-toluidine (p-toldn) 5, has been synthesized and characterized by uv-vis. and FT-IR. The kinetics of the substitu...

Abstract The hourglass fermions in solid-state materials have been attracting significant interest recently. However, realistic two-dimensional (2D) with hourglass-shaped band structures are still very scarce. Here, through the first-principles calculations, we identify monolayer Pb(ClO 2 ) and Sr(ClO as new platform to realize 2D Weyl nodal loop. We show that these possess an loop circling aro...

The reaction of NH4Cl with SO3 leads to the chlorosulfate (NH4)[SO3Cl]. Depending on temperature two different modifications are obtained. At 80 °C orthorhombic modification (NH4)[SO3Cl]-I is obtained (Pbca, Z=16, a=1078.03(4), b=911.55(3), c=1915.32(6), Vm=70.85 cm3/mol), at 120 monoclinic (NH4)[SO3Cl]-II forms (P21/c, Z=8, a=846.19(3), b=590.30(2), c=852.29(7) pm, β=100.516(10)°, Vm=68.48 cm3...
