【Abstract】 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 crys- tal 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.更多还原
