dimethyl sulfide for 3-carboaldehyde pyridine displacement in a platinum(ii) complex: donor number effect
نویسندگان
چکیده
the therrmodynamic parameters and equilibrium constant of displacement of dimethy sulfide by 3-carboaldehyde pyridine as n-donor ligand in cis-[pt(4-mec6h4)2(sme2)2] complex have been measured using uv vis spectroscopy in acetone, dichloromethane and benzene at various temperatures (t=15-20 °c) and compared with previous my reported about similar reaction. δho (kj.mol-1) of the mentioned reaction in acetone has been 7.158 while obtained less in dichloromethane (4.109 ) and more in benzene(9.96). the entropy of the reaction has been obtained 86.86 j.mol-1.k-1 in acetone , while calculated less in ch2cl2 (73.29 j.mol-1.k-1) and more in last solvent (97.40 j.mol-1.k-1). also, the gibbs energy, δg (j.mol-1), of the reaction obtained -18738.79, -17741.55 and -19043.06 respectively, with the same order. in all three solvents, the values of enthalpy and entropy change have been positive and decreased as the donor number of the solvents decreased.

متن کاملDimethyl sulfide triggers search behavior in copepods
The oceans are nutritionally dilute, and finding food is a major challenge for many zooplanktonic predators. Chemodetection is necessary for successful preycapture, but little is known about the infochemicals involved in the interaction between herbivorous copepods and their phytoplankton prey. We used females of Temora longicornis to investigate chemodetection of dimethyl sulfide (DMS) in this...

The dinuclear compound, [Nb(2)Cl(6)(C(2)H(6)S)(1.7)(C(2)H(6)Se)(1.3)], features an Nb(III)=Nb(III) double bond [2.6878 (5) Å]. The mol-ecule lies on a twofold rotation axis that passes through the middle of this bond as well as through the bridging dimethyl sulfide ligand. The Nb(III) ion exists in an octa-hedral coordination environment defined by two terminal and two bridging Cl atoms, and (C...
