Coinage Metal Complexes of Bis(quinoline-2-ylmethyl)phenylphosphine-Simple Reactions Can Lead to Unprecedented Results.

ABSTRACT: The different coordination behavior of the flexible yet sterically demanding, hemilabile P,N ligand bis(quinoline-2-ylmethyl)phenylphosphine (bqmpp) towards selected Cu^I , Ag^I and Au^I species is described. The resulting X-ray crystal structures reveal interesting coordination geometries. With [Cu(MeCN)₄ ]BF₄ , compound 1 [Cu₂ (bqmpp)₂ ](BF₄ )₂ is obtained, wherein the copper(I) atoms display a distorted square planar and square pyramidal geometry. The steric demand and π-stacking of the ligand allow for a short Cu⋅⋅⋅Cu distance (2.588(9) Å). Cu^I complex 2 [Cu₄ Cl₃ (bqmpp)₂ ]BF₄ contains a rarely observed Cu₄ Cl₃ clus
