Two organic-inorganic hybrids viz., bis(1,2,3,4-tetrahydroisoquinolin-2-ium) hexachlorostannate(IV) (1) and bis(1,2,3,4-tetrahydroisoquinolin-2-ium) hexabromostannate(IV) (2) were synthesized and confirmed by single-crystal X-ray diffraction analysis. The optical properties of the compounds were studied by diffuse reflectance and photoluminescence spectral studies. The thermal behaviour of the compounds was determined by thermo gravimetric (TG) and differential thermal analysis (DTA) concerning the temperature. The significant third-order nonlinear optical response shown by the compounds is disclosed by the Z-scan studies. The surface morphology and the elemental composition of the compounds were studied by scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) analyses. Bond valence sum (BVS) calculation confirmed the formal oxidation state of tin to be +4. Check continuous symmetry measure (CSM) calculation on SnX62? (X=Cl, Br) yields a value significantly near to the perfect octahedral geometry of the anions. The intermolecular interactions and their quantity contributions in the crystal packing were studied by Hirshfeld analysis and fingerprint plots.

The conversion of a wide range of primary and secondary aliphatic and a few arylamine hydrochloride salts to their corresponding acetamides with trimethyl orthoacetate is described. Mechanistic studies using NMR and gas chromatography-mass spectrometry techniques indicate these reactions proceed via an O-methylimidate intermediate that undergoes in situ demethylation by chloride, affording the corresponding acetamides. Synthetically, this reaction represents a practical, high-yielding protocol with a simple workup for the rapid conversion of amine hydrochloride salts to acetamides.

Four triorganotin derivatives of general formula C10H 10NS2SnR3,, where R = CH3 (1), C4H9 (2), C6H11 (3), and C6H5 (4), have been synthesized by the metathesis reaction of 1,2,3,4-tetrahydroisoquinolnium salt of ligand with triorganotin(IV) chloride in the 1:1 ratio. These complexes were characterized by elemental analysis, Raman, IR, multinuclear NMR (1H, 13C, and 119Sn), and mass spectrometry. The crystal structure confirmed a supramolecular zig-zag chain structure mediated by S-H (2.968 A) for complex 4 with the central Sn atom exists in a distorted trigonal bipyramidal geometry. A subsequent antibacterial study indicates that the compounds are biologically active.
