Abstract: The new ligand (PPh 2 CH 2 ) 2 N(3-CH 2 C 5 H 4 N), BPMP-3, has been shown to exhibit a variety of coordination modes including bridging ( syn - and anti -) and chelation. The multifunctional ligand facilitates the formation of discrete, as well as polymeric, complexes with various Ag(I) salts. A discrete structure with a 4-coordinate silver is isolated from the 1:2 reaction of AgBF 4 with BPMP-3 ( 1 ), while the 2:1 reactions of AgX ( 2 : X = CF 3 CO 2 − , 3 : X = BF 4 − , and 4 : X = OTf − ) with BPMP-3 result in 1-dimensional polymers with 2- to 5-coordinate silver atoms. Mixed ligand complexes ( 5 , 6 , and S1 ) are formed by the addition of 5,5′-dimethyl-2,2′-dipyridyl (5,5′-dmbpy). The 4:2:4 reactions of AgBF 4 ( 5 ) and AgOTf ( S1 ) with BPMP-3 and 5,5′-dmbpy results in a discrete structure with a box-like core. Demonstrative of the counterion effect, a 2:1:2 molecular structure was isolated from the 4:2:4 reaction with the tfa − derivative ( 6 ). Characterization of these coordination complexes includes multi-nuclear NMR spectroscopy, elemental analysis, single-crystal X-ray diffraction, and fluorometric studies. [ABSTRACT FROM AUTHOR]
