摘要

Six related organo-chalconium silver(i) coordination complexes, including two examples of rare organotellurium-silver coordination, have been prepared and structurally characterised by X-ray crystallography. The series of 5-bromo-6-(phenylchalcogeno)acenaphthene ligands L1-L3 [Acenap(Br)(EPh)] (Acenap = acenaphthene-5,6-diyl; E = S, Se, Te) were independently treated with silver(i) salts (AgBF_4, AgOTf). In order to keep the number of variables to a minimum, all reactions were carried out using a 1:1 ratio of Ag/L and run in dichloromethane. The nature of the donor atoms and the coordinating ability of the respective counter-anion affects the structural architecture of the final silver(i) complex, generating a monomeric dinuclear complex {[(AgBF_4(L1)_2)_2] 1}, monomeric, mononuclear, two-coordinate silver(i) complexes {[AgBF_4(L)_2] (2 L = L2; 3 L = L3)}, a monomeric three-coordinate silver(i) complex {[AgOTf(L2) _2] 5}, a monomeric four-coordinate silver(i) complex {[AgOTf(L1) _3] 4} and a 1D extended helical chain polymer {[AgOTf(L3)] n~6}. The organic acenaphthene ligands L1-L3 all adopt the same ligation mode with the central silver atom (classical monodentate coordination), which employs a variety of coordination geometries (linear, trigonal planar, see-saw, tetrahedral).
