Abstract

The title compound, [Pd2(C18H54Cl2N4P2Si6)2Cl2]·2C4H10O, features a dinuclear chloride-bridged palladium complex bearing two equivalents of the novel monoanionic mixed valent (λ3-P)—N—(λ5-P) ligand. A metal catalyzed coupling of two amino­imino­phosphines and a shift of one chlorine from the metal to the phospho­rus results in the (λ3-P)—N—(λ5-P) ligand. The mol­ecule contains a planar bimetallic Pd2Cl2 core with a crystallographic centre of inversion at the mid-point of the Pd⋯Pd line. The Pd atoms are in a distorted square-planar arrangement, where the P/Pd/P and Cl/Pd/Cl planes are twisted with respect to each other by a dihedral angle of 7.57 (4)°. The P—Pd—P bite angle is 71.380 (18)°. Intra­molecular C—H⋯Cl inter­actions are observed. In the crystal, the diethyl ether solvent mol­ecule is disordered over two sites, with an occupancy ratio of 0.788 (5):0.212 (5).
