Synthesis and Properties of Lanthanum- Pyrene Complexes—Structure of [(Cp*La)3(μ-Cl)3(thf)(μ-η2:η6:η6-C16H10)], the First Complex with a Pyrene Trianion
摘要:
Different bonding modes are characteristic for the lanthanum centers of the title compound, a trinuclear lanthanum-pyrene complex in which an arene trianion is present for the first time (see picture for the structure). Thus, La1 and La3 reside in a tetrahedral environment, the La2 center in a distorted trigonal-bipyramidal one.
