The first example of metallocene-like coordination mode of THBQ4−: A mixed-valence heptanucler palladium complex [Pd7(THBQ)2(tben)6](PF6)4

Abstract

The title compound adopts a structure reminiscent of metallocene analogues, in which two disk-like units [Pd(II)(3)(THBQ)(tben)(3)](2+) bind to one naked Pd(0) metal in a sandwich form through each C(6)O(6)(4-) (THBQ(4-)) ring with an eta(6)-binding fashion.
