Na2S was synthesized by a new solid-gas reaction of Na2CO3 with a sulfidizing gas mixture and a solid-solid reaction of carbon with Na2SO4. The reaction products were analyzed by X-ray powder diffraction and IR methods. Two new crystal modifications of Na2S were identified in addition to the previously reported antifluorite structure. They were designated as cubic Form II and orthorhombic Form III. The approximate unit cell dimensions were found to be a = 11.29 Å for the cubic form and a = 15.94, b = 16.00, and c = 16.18 Å for the orthorhombic form.

SOLID-STATE SYNTHESIS, STRUCTURE, AND VIBRATIONAL-SPECTRA OF NAGDP2O7 KIZILYALLI, M; DARRAS, M (Elsevier BV, 1993-12-01) NaGdP2O7 was synthesized by the solid-state reaction of Gd2O3 with Na2CO3 and 4(NH4)2HPO4 at 650°C. The X-ray powder diffraction data of NaGdP2O7 was indexed in the orthorhombic system with the approximate unit cell dimensions of a = 12.44 , b = 15.00, and c = 15.87 Å and the space group is Pmm2. Analysis of the vibrations of the P2O4-7 ion according to C2v symmetry and approximate band assignments for IR spectra are also reported in this work. The P-O-P band was found to be nonlinear, and some coincidences...
Synthesis of a new orthorhombic metastable form of CdS through solid-state reactions Bi̇lgi̇n, M.; Kızılyallı, Meral; Usanmaz, Ali (Elsevier BV, 1989-5) CdS has been prepared through solid-gas reactions of CdO with a sulfidizing gas mixture, at 750°C for 3 hr, and slow cooling under nitrogen atmosphere. The X-ray diffraction data of the product was indexed in a hexagonal system with unit cell parameters of a = 4.136 and c = 6.713Å, which agreed with the literature data. However, the presence of extra strong lines in the X-ray diffraction pattern and the splitting in the d-spacings showed that a new orthorhombic form of CdS was obtained. The unit cell dimens...
Conducting polymers of succinic acid bis-(2-thiophen-3-yl-ethyl)ester and their electrochromic properties SACAN, L; Çırpan, Ali; CAMURLU, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01) The homopolymer and copolymer of succinic acid bis-(2-thiophen-3-yl-ethyl)ester with thiophene were achieved via constant potential electrolysis in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, and acetonitrile/borontrifluoride ethylether (ACN/BFEE) (10:2 v/v) solvent mixture. The characterizations of both homopolymer (PSATE) and copolymer P(SATE-co-Th) were achieved by various techniques including cyclic voltammetry (CV), Fr-IR, scanning electron microscopy (SEM) and U...
Axial water substitution kinetics of sulphato- and hydrogenphosphato-bridged binuclear platinum(III) complexes Camadanli, S; Deveci, N; Gokagac, G; Isci, H (Elsevier BV, 2003-07-22) The kinetics of the axial water substitution reactions for [Pt-2(B-B)(4)(H2O)(2)](2-) (B-B = SO42-, HpO(4)(2-)) with Cl-, Br- and SCN- are reported in acidic aqueous solution. With a large excess of entering ligand and hydrogen ion, only the disubstituted product complex was formed. The reaction rates are first order with respect to the substrate complex and entering ligand and decrease with increasing H+ concentration. In the presence of 0.10 M H+, the rate constants for the replacement of the first water ...
Electrochemistry of nickel(II) complexes with N,N'-bis(3,5-di-tert-butylsalicylidene)polymethylenediamines Ozalp-Yaman, S; Kasumov, VT; Önal, Ahmet Muhtar (Elsevier BV, 2005-10-03) The electrochemical oxidation of several N,N'-polymethylenebis(3,5-di-tert- butylsalicylaldiminato)nickel(II) complexes, Ni(L-x), has been studied by cyclic voltammetry and in situ UV-Vis spectroscopy in DMF Cyclic voltammograms of Ni(L-x) (x = 1-4) complexes displayed two-step oxidation processes under nitrogen gas atmosphere. The first oxidation peak potentials of all the Ni(II) complexes corresponds to the reversible one-electron oxidation process of the metal center, yielding Ni(III) species. EPR spectr...
