Abstract: An electrolyte and a method of making an electrolyte of the formula: Mg[Al(R)4]2, where R represents a compound selected from a deprotonated alcohol or thiol; an amine; or a mixture thereof. The method includes the steps of: combining a Mg(AlH4)2 precursor with an alcohol, thiol or amine of the general formula R—H to create a reaction liquor containing Mg[Al(R)4]2; and washing the reaction liquor in an organic solvent.

Abstract: Described is a salt of the general formula: Mg2+(Lx)6(PF6)2 wherein each L is a ligand selected from dichloromethane, a cyclic ether, or a nitrile of the general formula R—C?N. The method of making the salt comprises the steps: providing Mg metal, activating the Mg metal in a first dry solution comprising a first ligand solution (L1), treating the dry solution of activated Mg metal and L1 with NOPF6 in a second dry solution comprising a second ligand solution (L2), heating the treated Mg metal solution removing residual solvent under vacuum, and recrystallizing the remaining solid to form the salt wherein Lx comprises a mixture of L1 and L2. The salt can be used as the salt in an electrolyte, or as an additive to an electrolyte, in a cell or battery.

Abstract: Disclosed is a process for the production of Zintl compounds by thermal decomposition of heterometallic phosphinidene complexes. The heterometallic phosphinidene complex typically comprises at least two metals, at least one of which is selected from a Group I metal, M1, and another being a metal M2, selected from Group 13, 14 or 15 of the Periodic Table. The heterometallic phosphinidene complex further comprises one or more phosphinidene ligands, [PR], wherein R is typically a substituted or unsubstituted hydrocarbyl group, and a Lewis base stabilizing ligand. Thermal decomposition of the heterometallic phosphinidene complexes in accordance with the invention forms a Zintl compound comprising metals M1 and M2 coordinated to Lewis base stabilizing ligands, Lg. The invention further provides a process for removal of the stabilizing ligand from the Zintl compounds to form an intermetallic compound.
