The asymmetric unit of the title compound, (C12H16N3O)2[PdCl4]3, consists of a 4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium dication and one and a half tetra-chloridopalladate(II) anions; the latter has inversion symmetry. In the cation, the pyridinium rings attached to the central 1-aza-niumyl-2-hy-droxy-ethane fragment show an anti conformation, as indicated by the central C-C-...

In this paper, macrocyclic cobalt(II) complexes [CoL1](NO3)2.4H2O (1) and [CoL2](NO3)2.2H2O (2) have been synthesized from the reaction of dialdehydes 1,2-bis(2-formylphenyl)ethane and 1,3-bis(2-formylphenyl)propane, Co(NO3)2.6H2O and 1,2-cyclohexanediamine with molar ration 1:1:1 in methanole and characterized by elemental analyses and FT-IR spectroscopy. Then used as precursors for preparatio...

Abstract. Atmospheric ethane can be used as a tracer to distinguish methane sources, both at the local and global scale. Currently, measured in field using flasks or situ analyzers. In our study, we characterized CRDS Picarro G2201-i instrument, originally designed measure isotopic CH4 CO2, for measurements of ethane-to-methane ratio mobile-measurement scenarios, near sources under conditions. ...

The process of ethylene production from ethane dehydrogenation is one of the interesting processes in the field of conversion the petroleum light gases to the valuable products. In this process, the outlet gaseous product is a combination of ethylene, ethane and hydrogen. Effective separation techniques are required for separation of ethylene from unreacted ethane. Here a new adsorbent approach...

The bond energy (BE) of CC in CH3-CH3 with respect to geometry frozen fragments follows a sigmoidal increase as function the θ = HCC pyramidalization angle. Using dynamic orbital forces BE index, same behaviour unique 〈θ〉 parameter, mean angle substituents, is found for 24 single bonds various hydrocarbons. Thus parameter appears straightforward and robust index geometrical constraints which ca...

The title compound, (C12H16N3O)[PtCl4]Cl, consists of a 4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium trication, a square-planar tetra-chloridoplatinate(II) dianion and a chloride ion. In the cation, the pyridinium rings attached to the central 1-aza-niumyl-2-hy-droxy-ethane fragment have an anti conformation, as indicated by the central C-C-C-C torsion angle of -166.5 (6)°, and t...
