The molecular structure of the complex bis-(2pyridyl) amine(eta(2)-styrene)silver(I) tetrafluoroborate has been determined. The geometry about the Ag+ ion is pseudo-trigonal planar, with coordination sites occupied by the two pyridyl nitrogen atoms and the midpoint of the alkene double bond. Crystal packing of the molecule is influenced by hydrogen bonding of the amine with the tetrafluoroborate anion, in addition to intermolecular Ag+center dot center dot center dot aromatic contacts. H-1 NMR confirms crystallographic data that suggest weak metal to olefin pi-backbonding. Crystal data: space group P2(1)/n, a = 12.764(3), b = 10.590(2), c = 13.624(3) angstrom, beta = 91.17(3)degrees, V = 1841.3(7) angstrom(3), Z = 4, R = 0.0453, wR(2) = 0.1098.
