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.
