TL;DR: In this paper, the conductance magnetic moment, spectral data, thermal and elemental analyses were used to characterize macrocyclic complexes of [Pr(L)(H2O)2]Cl3, [PR(mac1)]Cl3 and [Pr[Mac2]-Cl3 with semicarazide, thiosemicarbazide and carbohydrazide.

TL;DR: In this article, the authors showed that 5 and 6 coordinate structures can be assigned to CpTi(S2CNHR)Cl2 and CpNiCl2Cl2, respectively, for nonelectrolytes in which all dithiocarbamate ligands are bidentate.
Abstract: Titanium(IV) dithiocarbamato complexes of the typesCpTi(S2CNHR)Cl2 andCpTi(S2CNHR)2Cl, whereR=C8H5N2S, C9H5N2SCl2 and C9H7N2S, have been prepared by the reaction of monocyclopentadienyl titanium(IV) trichloride with the potassium salt of the appropriate dithiocarbamic acid in anhydrous dichloromethane. Conductance and infrared studies indicate that these complexes are non-electrolytes in which all dithiocarbamate ligands are bidentate. Therefore, 5 and 6 coordinate structures can be assigned toCpTi(S2CNHR)Cl2 andCpTi(S2CNHR)2Cl complexes, respectively.1H-NMR spectra indicate that there is rapid rotation of the cyclopentadienyl ring about the metal ring axis.

TL;DR: In this article , the effect of loading content of MoS2 over Mo2C on hydrogen evolution reaction (HER) activity and electrochemical capacitance performance has been studied in detail.
Abstract: In the present work, Mo2C-MoS2 heterojunction structures have been prepared by the wet impregnation method. For heterojunction species, the content of MoS2 was varied from 5 to 20% by weight. The effect of the loading content of MoS2 over Mo2C on hydrogen evolution reaction (HER) activity and electrochemical (EC) capacitance performance has been studied in detail. The Mo-C-S junction plays a key role in enhancing the HER activity and EC capacitance performance than the individual components. The prepared structures show enhanced HER activity with high current density ~36.2-78.3 mAcm-2 at very low applied potential (0.45 V), exhibiting a lower Tafel slope of 102.4 mVdec-1. The EC capacitor performance determined by CV and galvanic charge-discharge (GCD) reveals that the synthesized samples exhibit an electrochemical double-layer capacitor (EDLC, Cdl) behavior. The higher EDLC (43.9 mFcm-2) and specific capacitance (2Fg-1) obtained for the synthesized samples determine their potential applicability for the new generation supercapacitors.
