Title: Thermodynamic and thermoacoustic properties of liquid ethanol in temperature range from 380 to 460 K at pressures up to 190M Pa Authors: Pandey, J D; Vyas, Vimla; Dwivedi, D K; Dey, Ranjan Abstract: Thermodynamical and thermoacoustic properties of liquid ethanol in a temperature range varying from 380 to 460 K at various pressures up to 190 Mpa have been reported in the present investigation. The values of internal pressure ( <i>P</i>_in<i>), </i>Gruneisen parameter (Г) , heat of vaporisation (<i>H</i>_vap) and solubility parameter (δ) have been computed. The experimental values of density (ρ), isothermal compressibility (β_T) and coefficient of thermal expansion (α) at the above mentioned pressure have been taken from literature. Page(s): 993-996

Title: Synthesis and structure of the copper(I) complex- [Cu(dppm) (2,2'-bipy)]₂(NO₃)₂ Authors: Dongmei, Wang; Ruina, Yang; Yimin, Hou; Xiaoyuan, Hu; Douman, Jin Abstract: Binuclear copper(I) complex&nbsp; [Cu(dppm) (2,2'-bipy)]₂(NO₃)₂ ,(<b>1</b>) dppm=Ph₂PCH₂PPh₂] has been synthesized by a ligand replacement reaction. X-ray crystal structure of the complex (<b>1</b>) shows that dppm coordinates as a bridging bidentate ligand, and 2,2 -bipy as a bidentate ligand to the Cu(<b>I</b>) atoms with tetrahedral structure. NO₃^-behaves as a free ion in this newly prepared binuclear copper(<b>I</b>) complex. Crystals (<b>1</b>) are monoclinic <i>P</i>2₁/n, <i>a = </i>1.4663(5); <i>b </i>= 1.3076(5), <i>c </i>= 1.9910(6) nm; β =110.66(3)^o, <i>V</i> = 3.5719 nm³, Z = 2, F(000) = 1536, Dc= 1.332 g cm^-3, R= 0.06320, Rw = 0.08132.

Title: [K(18C6)]₂[Pt(SCN)₄](H₂O): A novel one-dimensional coordination polymer with K-N bonds Authors: Liu, Ying; Dou, Jianmin; Zhuh, Lanying; Sun, Dezhi; Zheng, Peiju Abstract: Pt (II) 18-crown-6 complex [K(18C6)]₂[Pt(SCN)₄](H₂O) has been isolated and characterized by X-ray diffraction analysis. The crystal structure belongs to monoclinic, space group <i>P</i>2₁<i>/ n </i>with cell dimensions, <i>a </i>= 1.1116(1), <i>b </i>= 1.2258(1), <i>c</i> = 1.5856(1) nm, β = 93.479(9)<u>^o</u> , <i>V </i>= 2.1567(3) nm³, Z = 2, R = 0.033 and Rw = 0.051 . In the solid state, the complex displays a one-dimensional infinite chain of two [K(18C6)]+ complex cations and a [Pt (SCN)₄]^2- anion bridged by one H₂O molecule between adjacent [K(18C6)]⁺units.

Title: Synthesis of β-halogenated porphyrin dimers with distinct photophysical properties Authors: Ravikanth, M Abstract: Diaryl ethyne bridged zinc and free base porphyrin containing dimers with four bromines exclusively on one of the porphyrin ring have been synthesized.The energy transfer from an excited zinc porphyrin to free base porphyrin depends mainly on the position of bromines in the dimers.
