TL;DR: The reaction of (Me5C5)2Yb(OEt2) with Co2(CO)8 in toluene, followed by recrystallization from Et2O-tetrahydrofurfuran(thf)-pentane, gives (me5C 5)2ybCo(CO), in which the Co (CO)4 fragment is bonded to the (Me 5C5)-2-Yb (thf) unit via a carbonyl group.

TL;DR: The energy decomposition analysis showed that the dissociation energies and the red shifts in the O-H stretching frequencies follow a unified correlation if these two parameters were correlated with the sum of the charge transfer and the exchange component of the total binding energy.
Abstract: Hydrogen bonding interaction between the ROH hydrogen bond donor and sulfur atom as an acceptor has not been as well characterized as the O–H···O interaction. The strength of O–H···O interactions for a given donor has been well documented to scale linearly with the proton affinity (PA) of the H-bond acceptor. In this regard, O–H···O interactions conform to the acid–base formalism. The importance of such correlation is to be able to estimate molecular property of the complex from the known thermodynamic data of its constituents. In this work, we investigate the properties of O–H···S interaction in the complexes of the H-bond donor and sulfur containing acceptors of varying proton affinity. The hydrogen bonded complexes of p-Fluorophenol (FP) with four different sulfur containing acceptors and their oxygen analogues, namely H2O/H2S, MeOH/MeSH, Me2O/Me2S and tetrahydrofuran (THF)/tetrahydrothiophene (THT) were characterized in regard to its S1–S0 excitation spectra and the IR spectra. Two-color resonantly en...

TL;DR: The first methyl-substituted isolable disilene was determined by X-ray crystallography in this paper, and its structure was determined using a regioselective addition of a methyl anion to the SiSi bond in 3 took place to give the solvent-separated silyl anion species tetrakis(tetrahydrofuran)lithium.
