A dramatic deviation from square‐planar coordination for Pd II complexes: the CPdC and PPdPlanes in the helical chiral complexes 2 (∪ = 1,1′‐ferrocenediyl) are unexpectedly tipped toward each other by as much as 30°. These complexes are prepared from the appropriate bidentate phosphane ligands and the bishomopalladole 1 , which is remarkably stable and availalbe in enantiomerically pure form in good yields.
