Synthesis and characterization of microstructured crystalline complexes of [HgI2(C14H12N2)] and [HgBr2(C14H12N2)] were carried out from the reaction between 2,9-dimethyl-1,10-phenanthroline, mercury acetate, KI, and KBr, respectively, in methanol by sonochemical method. The reaction conditions were optimized under ultrasonic irradiations and without it. Characterization of the complexes was performed by elemental analysis, XRD, SEM, FTIR, and thermal analysis (TG/DTA). The results showed that sonochemical method caused significant reduction of the reaction time. Then the products were put under supercritical condition in a Teflon-lined, stainless-steel Parr bomb container and heated at 150°C for 48 h. The results showed that the chemical formulas of the complexes were not changed; however, the particle sizes were reduced and porosity increased.

Complex of cobalt(II) with sulfisoxazole (slfs) has been synthesized in 1 : 4 mole ratio of metal to ligands in methanol, the complex formula is [Co(slfs)3(H2O)3]SO4.nH2O. The electric conductivity of the complex in methanol correspond to 1:1 electrolyte. The thermal analysis indicates that complex contain some hydrates. Magnetic Susceptibility measurements show that the complex is paramagnetic with µeff = 4,60(9) BM. Infra red spectra indicates that the primary N-H group coordinated to the center ion, it is signed by a shift of primary N-H group absorption. UV-Vis spectrum appears one peak at λ= 515,5 nm (19.342 cm-1) due to transition peak of 4T1g (F) → 4T2g (P) (ν3) overlay to transition peak of 4T1g(F) → 4A2g(F) (ν2). The value of 10 Dq (Δo) that corresponds to transition 4T1g → 4T2g (n1) is 95,29 kJ.mol-1. Cyclic voltammograms have revealed quasi reversible. The complex probably is octahedral.   Keywords: cobalt(II), sulfisoxazole, complex, paramagnetic, octahedral

Nanocrystalline ZnO powders have been synthesized by a novel combustion synthesis method using glycine and urea as mixed fuels and zinc nitrates as oxidant. The as-synthesized ZnO powders are characterized by DSC, XRD and SEM. Results show that the as-synthesized ZnO powders show well crystalline with hexagonal crystal structure and purity without any other impurities and the particle sizes are about 50~70nm calculated by the Scherrer formula.

Novel Method

A novel one-pot method for the synthesis of substituted μ-oxo-bis [tetraphenyl porphyrinatoiron] compounds ([TRPPFe]2O) from pyrrole and aromatic aldehydes was proposed and investigated in this paper. Four kinds of [TRPPFe]2O were designed and synthesized by one-pot reaction and characterized by elemental analysis, infrared spectra and ultraviolet-visible spectroscopy. Moreover, the [TRPPFe]2O yields of 18.7~22.4% could be obtained with this novel method under the optimum reaction conditions.
