Mishra, Vidyanshu published the artcileSemiconducting Sm3GaSe5O with trigonal bipyramidal GaSe5 units, Category: esters-buliding-blocks, the main research area is semiconducting samarium GaSe oxygen trigonal bipyramidal unit space group.
The oxyselenide Sm3GaSe5O was prepared by reaction of Sm2O3, Sm, Ga2Se3, and Se at 950 °C. It adopts a new monoclinic structure type (space group P21/m, a = 11.042(9) Å, b = 3.9761(3) Å, c = 21.2458(17) Å, β = 92.2436(14)°, Z = 4) built up of Sm-Se, Sm-O, and Ga-Se blocks. GaSe5 trigonal bipyramids, which are unprecedented, are the most unusual feature of this structure. Electronic structure calculations corroborate the occurrence of primarily ionic bonding within the Sm-Se and Sm-O blocks and covalent bonding within the Ga-Se blocks. Optical measurements reveal a nearly direct band gap of 1.2 eV, narrower than those of many other oxychalcogenides.
Journal of Solid State Chemistry published new progress about Band gap. 110-42-9 belongs to class esters-buliding-blocks, name is Methyl decanoate, and the molecular formula is C11H22O2, Category: esters-buliding-blocks.
