[(CO)AuCl] reacts with equimolar amounts of Ph 2 PCH 2 P(Se)Ph 2 (dpmSe) to afford ClAuPh 2 PCH 2 P(Se)Ph 2 , in which dpmSe is bound to gold in a monodentate fashion by phosphorus. Subsequent reaction of this 1:1 complex with AgClO 4 results in the formation of the 10‐membered ring complex 4 which crystallizes in the monoclinic space group P2 1 / n with approximately centrosymmetric dicationic units, in which two gold (I) atoms are doubly bridged by two dpmSe ligands coordinated by phosphorus and selenium. The coordination at the gold atoms deviates from linearity and implies an Au···Au interaction with the gold(I) atoms separated by a distance of 3.020(1) Å.
