Treatment of 1,2‐C 6 H 4 (SiH 3 )(SiH 3 ) (1) or 1,2‐C 6 H 4 (SiMe 2 H)(SiH 3 ) (2) with Pd(dcpe)(PEt 3 ) 2 (dcpe=Cy 2 PCH 2 CH 2 PCy 2 ) in the ratio of 1:1 affords two cis ‐bis(silyl) palladium(II) complexes {1,2‐C 6 H 4 (SiH 2 )(SiH 2 )}Pd II (dcpe) (3) and {1,2‐C 6 H 4 (SiMe 2 )(SiH 2 )}Pd II (dcpe) (4) with good thermal stability respectively. To the best of our knowledge, only ten silyl palladium complexes prepared from these two chelating hydrosilane ligands are presented in the Cambridge Structural Database. The structures of complexes 3 and 4 are unambiguously determined by single crystal X‐ray analysis and multinuclear NMR spectroscopic studies.
