| 摘 要： | The title compound, Mn2·(dinitrobenzoic acid)4·(1,10-phen)2]n, has a linear chain struc- ture containing binuclear Mn2·(dinitrobenzoic acid)4(1,10-phen)2] repeat units. It crystallizes in the tricli- nic system, space group P1 with a = 7.9261(8), b = 12.1329(15), c = 14.847(2) , α = 103.845(5), β = 101.424(5), γ = 92.618(4)o, Mr = 657.37, V = 1352.3(2)3, Z = 2, Dc = 1.614 g/cm3, F(000) = 666, μ = 0.567 mm-1, the final R = 0.0407 and wR = 0.1015 for 4081 observed reflections with I > 2σ(I). The Mn atom is six-coordinated by two N and four O atoms, forming a slightly distorted octahedral geometry. All Mn–O and Mn–N bond distances range from 2.093(2) to 2.310(2) . Two adjacent octahedral units are bridged together by two pairs of bi-monodentate carboxyl groups of different dinitrobenzoic acids to form an eight-membered ring with chair-typed configuration, thus generating a one-dimensional chain along the a axis.
