A sandwich-type cluster containing Ge@Pd₃ planar fragment flanked by aromatic nonagermanide caps.

ABSTRACT: Sandwich-type clusters with the planar fragment containing a heterometallic sheet have remained elusive. In this work, we introduce the [K(2,2,2-crypt)]₄{(Ge₉)₂[η⁶-Ge(PdPPh₃)₃]} complex that contains a heterometallic sandwich fragment. The title compound is structurally characterized by means of single-crystal X-ray diffraction, which reveals the presence of an unusual heteroatomic metal planar fragment Ge@Pd₃. The planar fragment contains a rare formal zerovalent germanium core and a peculiar bonding mode of sp²-Ge@(PdPPh₃)₃ trigonal planar structure, whereas the nonagermanide fragments act as capping ligands. The chemical bonding pattern of the planar fragment consists of three 2
