| Abstract: | Treatment of a suspension of AgNO3 and AgCl in MeOH with a solution of N,N,N′,N′-tetra(diphenylphosphanylmethyl)ethylene diamine (dppeda) in CHCl3 afforded a binuclear complex Ag2(dppeda)Cl](NO3)·2MeOH (1). The analogous reactions using AgSCN and dppeda in EtOH/CH2Cl2 gave rise to a polymeric complex Ag2(dppeda)(SCN)2]n (2). Both compounds were fully characterized by elemental analyses, IR spectra, 1H(31P) NMR, and single-crystal X-ray crystallography. The cation of 1 shows an interesting molecular basket framework in which dppeda adopts a side-by-side coordination mode. Compound 2 possesses an unique 2D (6,3) layer network with 34-membered metallomacrocycles in which dppeda takes a end-to-end coordination mode. The 2D topological framework of 2 is rare in the chemistry of tetraphosphines. The photoluminescent properties of 1 and 2 in solid state at ambient temperature were investigated. |
