The reaction of [(CpPPh 2 ) 2 ZrCl 2 ] ( 1 a ) with two molar equivalents of (Me 2 S)AuCl gave the trimetallic complex [(CpPPh 2 AuCl) 2 ZrCl 2 ] ( 6 ). Crystalline complex 6 shows a conformational structure that features both PAuCl vectors oriented toward the open front side of the bent metallocene wedge. Quantum‐chemical calculations rationalized the absence of an aurophilic Au⋅⋅⋅Au interaction in 6 by showing that a combination of noncovalent forces overcompensates any possible attractive Au⋅⋅⋅Au interaction.
