Fixing carbon dioxide with copper: Crystal structure of [LCu(mu-C2O4)CuL][Ph4B](2) (L = N,N ',N ''-triallyl-1,4,7-triazacyclononane)
Reaction of CuI, 1,4,7-triallyl-triazacyclononane (L), and sodium tetraphenylboron with either CsHCO3 in dry methanol or CO2 in slightly moist methanol results in the formation of the oxalate anion, which is isolated as [LCu(mu -C2O4)CuL] [Ph4B](2) (1).
