• UV and visible emission originated from Cerium doping in CaSnF 6 . Impact of synthesis on photochromism effect stannate compound. Modification doped linked to thermal history. Considering the interest develop new photochromic compounds, Ce doped-CaSnF have been selected thoroughly characterized. After optimization route, structural morphological properties, are described. The origin optical p...

The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octa-hedral coordination environment defined by three chlorido ligands, an oxygen atom from a water mol-ecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N-H⋯O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex...

In the structure of the hydrated title salt, (C4H7N2)2[Sn(C2O4)2(OH)2]·H2O, the asymmetric unit comprises one stannate(IV) dianion, two organic cations and one water mol-ecule of crystallization. The [Sn(C2O4)2(OH)2](2-) dianion consists of an Sn(IV) atom chelated by two oxalate anions and coordinated by two OH(-) ligands in a cis octa-hedral arrangement. Neighbouring anions are connected throu...

The first charge-neutral Lewis base adducts of tin(IV) tetraazide, [Sn(N3)4(bpy)], [Sn(N3)4(phen)] and [Sn(N3)4(py)2], and the salt bis{bis(triphenylphosphine)iminium} hexa(azido)stannate [(PPN)2Sn(N3)6] (bpy = 2,2'-bipyridine; phen = 1,10-phenanthroline; py = pyridine; PPN = N(PPh3)2) have been prepared using covalent or ionic azide-transfer reagents and ligand-exchange reactions. The azides w...

We have studied the growth of epitaxial films stannate pyrochlores with a general formula A2Sn2O7 (A = La and Y) find that it is possible to incorporate ∼25% excess A-site constituent; in contrast, any tin expelled. unravel defect chemistry, allowing for incorporation species mechanism behind expulsion. An surplus manifested by shift film diffraction peaks, expulsion apparent from surface morph...
