accessible by molecular recognition, was obtained via treatment of [Pt(dppf)(C≡C-C6H4-4-P(C6H5)2)2] (dppf = 1,1′-bis(diphenylphosphino)ferrocene) (11) with [PtCl2(SEt2)2] (12). The structure of 13 in the solid state was confirmed by crystal structure determination, proving the formation of a neutral molecular square composed of Pt(dppf) and PtCl2 corner units and 4-(C6H5)2P-C6H4-C≡C linkers. In addition, compounds
