A new tris-chelate Cd(II) complex, [Cd(DADMBTZ)3](ClO3)2 has been successfully synthesized and characterized by IR, 1H, 13C NMR spectroscopy, elemental analysis and single crystal X-ray determination. The thermal behavior, UV-Vis and fluorescence spectra of compound were studied. In reaction with DADMBTZ, Cadmium (II) forms a tris-chelate complex with nearly C3 symmetry for coordination polyhed...

In this paper, we report on the synthesis of Cu nanoparticles through a single-precursor route by controlling the growth temperature. Selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. The understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

Hybrid inorganic-organic material based on Keggin type polyoxometalaes ([SiW12O40]4-) and praseodymium-dipicolinic acid (pydc; 2,6-pyridindicarboxylic acid) with the formula of [Pr2(pydc)2(H2O)8][H2SiW12O40]•4H2O (1) is obtained under a hydrothermal condition. Compound 1 was characterized by infrared spectrum and elemental analysis and its structure was further determined by single-crystal X-ra...

In this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. The benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (CH3COO)2Cu.H2O individually as Cu sources. Al...

Two new nano-sized lead(II) and mercury(II) coordination polymers, [Pb(2-bpdh)(NO3)2(H2O)]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza- 2,4-hexadiene)} and [Hg(4-bpdb)(SCN)2]n (2); (4-bpdb= 1,4-bis(4- pyridyl)-3,4-diaza-1,3-butadiene) were synthesized by a sonochemical method. The structure of 1 may be considered coordination polymer of lead(II) and Single crystal X–ray analysis of compound ...

A new semiorganic nonlinear optical single crystal of Imidazole Potassium Chloride (IPC) has been grown successfully by slow evaporation method. Colourless, transparent IPC crystal of dimension 5 x 5 x 2 mm has been grown within a period of 21 days. The grown crystal was subjected to single crystal X-ray diffraction (XRD) analysis to determine the lattice parameters. The powder X-ray diffractio...
