Abstract:

The asymmetric unit of the crystal structure of the title compound, [Sn(C8H5)4], consists of one fourth of a discrete tin complex and one half of another which both possess nearly ideal tetrahedral symmetry; the site symmetries of the two Sn atoms are \overline4 and 2. The bond angles at all acetylide C atoms are almost linear. The Sn—C distances [2.076 (6) and 2.065 (6)–2.069 (6) Å in the two complexes) are short when compared to the sum of the covalent radii of C and Sn (2.177 Å), but consistent with another tetrakis(alkynyl)tin complex. The acetylenic bond distances [1.196 (7) and 1.183 (7)

Abstract:

Soluble tin(IV) chalcogenide complexes play a major role in solution processing synthesis of macroelectronic tin(IV) chalcogenide based devices, e.g. thin film transistors (TFTs) and the technological interesting photovoltaic material, Cu2ZnSnS4 (CZTS). The synthesis and study of new soluble thiostannate(IV) complexes without electronic impurity atoms and with low decomposition temperature are of key importance for the further development of tin(IV) chalcogenide based devices. We have from the same aqueous ammonium tin(IV) sulfide solution, synthesized and characterized four new crystal struct

The water-soluble tin(IV) tetrakis(2-N-hydroxyethyl-4-pyridinium)porphyrin 1 photocatalyst was synthesized in good yield and its structure determined by single crystal X-ray crystallography.

In comparison with the previous refinement, the current redetermination reveals anisotropic displacement parameters for all non-H atoms, localization of the H atoms, and higher precision of lattice parameters and interatomic distances. The complex features a distorted S6octahedral coordination geometry for tin and acisdisposition of the monodentate dithiocarbamate ligands.

The diorganotin(IV) complex [Ph2Sn(L)(CH3COO)] (1), where HL = 2-acetylpyrazine N4-methyl thiosemicarbazone, has been synthesized and characterized by elemental analysis, IR, UV/Vis and NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. Complex 1 contains mononuclear neutral molecules composed of one N2S tridentate anionic thiosemicarbazone ligand, one acetato group, and one Ph2Sn(IV) group with a seven-coordinated tin atom. In vitro biological studies have indicated that complex 1 shows effective cytotoxicity with IC50 = 5.4 μM against the K562 leukaemia cell line.

Abstract:

Cationic tin(IV) porphyrins with tetracarbonyl cobaltates were synthesized, exhibiting bifunctional catalytic reactivity. The Lewis acidic tin-porphyrin center activated epoxides; concurrently, cobalt carbonyl anions efficiently opened epoxides and delivered carbonyl moieties. Thus, a series of β-lactones with a high synthetic value were obtained. This catalytic system showed excellent efficiency exceeding a turnover number of one thousand with a broad substrate scope. In addition, the presented tin porphyrin-based catalyst exhibited exclusive chemoselectivity to terminal epoxides over interna

Complex 3b, containing a CH group in place of one of the aza nitrogen atoms of the phthalocyanine core, shows a split Q-band due to its lower symmetry. The triplet state quantum yields were found to be lower than would be expected on the basis of the heavy atom effect of tin as the centr

The nucleophilic attack of a rhodium(I) porphyrin on a chlorotin(IV) corrole yields the heterobinuclear rhodium porphyrin-tin corrole complex where the two metals are bound via a single metal-metal bond. The X-ray structure of the rhodium tetraphenylporphyrin-tin(2,3,7,13,17,18-hexamethyl-8,12-diethylcorrole) complex is reported. The Rh-Sn single bond distance is equal to 2.5069(7) Å and the Rh and Sn atoms are located at 0.076 and 0.793 Å from the porphyrin and the corrole 4N mean planes, respectively.

The tin (IV) and cadmium (II) complexes were synthesized in mixture, the ligand 4,4'-(ethane-1,2-diylbis(azanylylidene))bis(pent-2-en-2-ol), and the halide metal (SnCl2 or CdI2). Complex synthesis involves partial hydrolysis of the ligand followed by condensation cyclization.

Tin(IV) alkoxides react with pentane-2,4-dione (acetylacetone) and other β-diketones to yield Sn(OR)3(chel) or Sn(OR)2(chel)2 derivatives. Sn(Opri)3(acac) has been shown to be dimeric in the solid state by a single-crystal X-ray diffraction study, the tin atoms being linked by two alkoxide bridges. In solution l19sn n.m.r. spectral data show that this single complex rapidly converts into a mixture of tin-containing species followed by slow disproportionation to the bis derivative Sn(OPri)2(acac)2 and Sn(Opri)4.
