| Abstract: A trinuclear oxo-centered carboxylated complex [Cr3(μ3-O)(Tc)6(H2O)3]·(NO3)·4H2O (Tc=thiophene-2-carboxylate) has been synthesized by the reaction of chromium nitrate and thiophene-2-carboxylate under hydrothemal conditions. X-ray crystal structure analysis was carried out to determine the crystal structure of the title complex. The crystal of the title complex belongs to monoclinic system with space group P21/n, a=1.433 7(5) nm, b=2.100 1(8) nm, c=1.540 8(6) nm, β=96.883(4)°, Z=4, V=4.606(3) nm3, Dc=1.619 g·cm3, F(000)=2 284, Final R1=0.077 5, wR2=0.166 0, GooF=1.110. The Cr(Ⅲ) possesses a six-coordianted octahedral coordination geometry and the complex has a triangular μ3-oxo bridge [Cr3O] core. The 2D networks were formed by hydrogen bonds interaction of neighbouring molecular. CCDC: 675676. |
