Complexes of Zn(II), Pd(II) and Pt(II) with 2?-[1-(2-pyridinyl)ethylidene ]oxamohydrazide (Hapsox) were synthesized and their structures were determined. All the complexes are of a neutral type with two apsox ligands coordinated to Zn(II) and one apsox ligand coordinated to Pd(II) or Pt(II). In each case, the polydentate was coordinated via pyridine and hydrazone nitrogens and ?-oxyazine oxygen, forming an octahedral geometry around Zn(II), and a square planar one around Pd(II) and Pt(II). The structure determination was performed by IR, 1H-NMR and 13C-NMR spectroscopy, and for the Zn(II) complex by X-ray structure analysis.

Pyridine Series

A convenient domino route for the synthesis of novel 1,3-dihydrofuro[3,4-c]pyridines from pyridoxal and alkyl, aryl or heteroaryl ketones under basic conditions is reported. A series of nine derivatives is obtained in 53–90% yields after stirring reactants for 48 hours at room temperature. Most products are easily isolated by filtration followed by recrystallization from ethanol. All products were fully characterized by FTIR, HRMS, and 1H and 13C NMR spectroscopy. The X-ray crystal structure of a representative example of the 1,3-dihydrofuro[3,4-c]pyridine series is also presented.

Linear coordi-nated Ag (І) NHC complex was synthesised via deprotonation of the imidazolium salt and reac-tion with Ag2O in darkness at room temperature by in situ method. The complex was synthesised for using as transfer agent to prepare another transition metals complexes by transmetallation method in the future. The imidazolium salt and their silver complex have been characterized by 1 H and 13C NMR spectroscopy as well as mass spectrometry.

A Pd(II) complex with methyl 2-((1-(2,4-dioxochroman-3-ylidene)ethyl)amino)acetate was synthesized. The structures of both the ligand and Pd(II) complex were determined by elemental analysis, IR and NMR spectroscopy. Recrystallization of Pd(II) complex from DMF/water solution resulted in its hydrolysis and formation of dimethylamine-(2-((1-(2,4-dioxochroman-3-ylidene)ethyl)amino)acetato)palladium(II) complex, the structure of which was determined by elemental analysis, IR, 1H and 13C NMR spectroscopy, as well as X-ray analysis.

A new series of dibutyltin(IV) alkylcyclohexyldithiocarbamates of the type (C4H9)2Sn[S2CNR(C6H11)]2 (R = CH3, C2H5, i-C3H7) have been successfully synthesized using in-situ method. These compounds were characterized by elemental analysis, infrared and 13C NMR spectroscopy. A single crystal X-ray analysis of dibutyltin(IV) ethylcyclohexyldithiocarbamate, (C4H9)2Sn[S2CN(C2H5)(C6H11)]2 (compound 2) showed that the system of this crystal is triclinic with space group P-1 while dibutyltin(IV) methylcyclohexyldithiocarbamate, (C4H9)2Sn[S2CN(CH3)(C6H11)]2 (compound 1) has monoclinic system and it’s space group is P21/c. In the crystal structure of compound 2, the dithiocarbamate ligands are bidentically chelated to the tin atom with non-equivalent of the Sn-S distances: Sn(1)-S(1) = 2.9255(11) and Sn(1)-S(2) = 2.5419(10); Sn(1)-S(3) = 2.8922(9) and Sn(1)-S(4) = 2.5293(10) Å while in compound 1, the dithiocarbamate ligands were anisobidentically  chelated to the tin atom.
