A new Ag(I) complex [Ag4(L)2(CH3CN)2(CF3CO2)4]n (1) was synthesized by the reaction of a 2-oxazolinyl-containing tripodal ligand 1,3,5-tris(2-oxazolinyl)benzene (L) with a silver(I) trifluoroacetate and characterized by means of elemental analysis, electrospray mass (ES-MS) spectroscopy and single crystal X-ray diffraction. The results of the crystallographic analysis showed that the complex 1 is triclinic, with space group P-1, a=0.83731(6) nm, b=1.22828(9) nm, c=1.33997(10) nm, α=102.9760(10)°, β=107.3050(10)°, γ=93.8600(10)°, Z=1, R=0.0365, wR2=0.0929. The complex consists of [Ag4(L)2- (CF3CO2)2]2+ cage-like subunits, which are further connected into 1D infinite chain by two bridging CF3COO anions. The 1D chains are further linked by C—H…O hydrogen bonds to form 2D network structure. The results of the ES-MS measurements suggested the polymeric structure of the complex in solution under the ES mass spectroscopy experimental conditions.
