Microcalorimetric Measurements of the Solvent Contribution to the Entropy Changes upon Electrochemical Lithium Bulk Deposition

“…This concept was first proposed by Ulich about 80 years ago to calculate the solvation number of ions in water. [17] He essentially assumed that the water in the first solvation shell of the ion is immobilized similarly to water in an ice crystal. Later Marcus adopted this approach for the determination of solvation numbers in non-aqueous solvents.…”

Coördination Compounds of Boron Trichloride. I. A Review.

“…Substitution of a methyl group for the hydrogen atom in hydrogen cyanide seems to improve the donor properties of the nitrogen atom. A coordination compound between acetonitrile and boron trichloride, CH3CN -BCls, has been reported by Nespital and coworkers (46,61,62). It is a white crystalline compound melting at 169°C.…”

Reactions Of Boron Trichloride With Organic Compounds

“…The zero dipole moment of boron trichloride in benzene gave wray to one of 5.89 D in diethyl ether (126,152), and this was of the right order for a tetrahedral structure for the 1:1 complex. Complexes generally underwent further reaction (equations 32 to 35) near their melting points.…”

“…NITRILES, AMIDES, NITRO COMPOUNDS, AND DIAZOMETHANE Boron trichloride was shown to form a 1:1 complex with acetonitrile (126,151,152). This was prepared either in the gas phase in a high-vacuum apparatus at -70°C.…”

“…in an inert solvent such as benzene or methylene dichloride (75,126). The dipole moment of the complex in benzene has been determined (126,151,152), although its solubility in that solvent is very small (107). By electron diffraction and vapor pressure measurements it was shown that the complex was almost completely dissociated in the vapor state, and its stability in the solid state has been attributed to the high crystal lattice energy (139).…”
