The crystal structures of the tri- and tetrahydrate of tin tetrachloride, viz. diaquatetrachlorotin(IV) monohydrate, [SnCl(4)(H(2)O)(2)].H(2)O, and diaquatetrachlorotin(IV) dihydrate, [SnCl(4)(H(2)O)(2)].2H(2)O, are reported and shown to contain the cis-[SnCl(4)(H(2)O)(2)] species and water molecules in both cases. The trihydrate contains chains of the tin species linked by a single hydrogen-bo...

Background: The biological assessment of trimethoprim organotin complexes is the subject work discussed in this publication. Objective: purpose project to investigate properties tin and via characterizing their IR NMR elemental analysis sensitivity. Material methods: These combine octahedral ML6 pyramidal ML5 by allowing amino groups present medicinal ingredients react with (IV). Results: compl...

In the centrosymmetric tetra-nuclear title mol-ecule, [Sn(4)(C(6)H(5))(8)Cl(2)O(2)(OH)(2)]·2C(2)H(6)OS, the two independent tin(IV) atoms show distorted trigonal-bipyramidal SnC(2)O(3) and SnC(2)O(2)Cl coordination geometries. The four tin(IV) atoms are bridged by the hydroxo and oxo ligands, forming a ladder-like array of three edge-connected Sn(2)O(2) squares. The solvent mol-ecules are linke...

The title complexes [mu-(E)-4,4'-(ethene-1,2-diyl)dipyridine-kappa(2)N:N']bis[halotris(4-methylphenyl)tin(IV)], [Sn(2)(C(7)H(7))(6)X(2)(C(12)H(10)N(2))], where halo is chloro (X = Cl) and bromo (X = Br) are isostructural. In both crystals, the molecules lie on inversion centers, and there are voids of ca 80 A(3) that could, but apparently do not, accommodate water molecules. The corresponding i...

This study describes the preparation and description of four new complexes: Bu2Sn(AA)Cl (AA = glycine, DL = valine and L = leucine) and Bu2SnPhen2 (Phen = DL-phenylalanine). They were characterized by elemental analyses for carbon, hydrogen, nitrogen, chlorine and tin by infrared, 119mSn-Mössbauer and 119mSnRMN spectroscopies and by the applications of TG and DSC techniques in a dynamic helium ...

new diorganotin(iv) complexes of the type ph2snl2, bu2snl2 and me2snl2 of the ligands 2-thioacetic-5-phenyl-1,3,4-oxadiazole (hl1) and benzamidophenylalanine (hl2). have been synthesized and characterized by physico-chemical techniques such as (elemental analysis, and electrolytic conductance) and spectral uv-visible, ir and 1h, 13c and 119sn nmr). monomer structures for the complexes, bidentat...

A series of porphyrin-based ionic complexes were prepared through the reaction two porphyrin precursors, 5,10,15,20-tetrakis(4-(2-pyridyl)phenyl)porphyrin H2TPhPyP (1) and trans-dihydroxo [5,10,15,20-tetrakis(4-(2-pyridyl)phenyl)porphyrinato]tin(IV) Sn(OH)2TPhPyP (2), with various acids (HCl, HNO3, CF3COOH, H2SO4, H2CO3, H3PO4). The characterized via elemental analysis, 1H nuclear magnetic reso...

Stable, six coordinated Bu(2)SnLA type complexes have been prepared [where LH = RCOC:C(OH)N(C(6) H(5))N:CCH(3); R = -4-F-C(6)H(4)-(L(1)H), R = -4-Cl-C(6)H(4)-(L(2)H), R= -4-Br-C(6)H(4)-(L(3)H), R=-CF(3)(L(4)H) and AH = C(O)C(6) H(4) C(O)NCHR'COOH; R'= -H(A(1)H), -CH(3)(A(2)H), -CH(CH(3))(2)(A(3)H)] by the interaction of 1:1:1 molar ratios of di-n-butyltin(IV) dichloride with corresponding organ...
