摘      要：A new two-dimensional Mnn metal-organic framework （MOF）, [Mn4（μ3-OH）2L2 （4,4＇-bipy）2（H20）2]·H2O （1, H3L = 5-oxyacetateisophthalic acid, 4,4＇-bipy = 4,4＇-bipyridine） has been synthesized by the hydrothermal reaction. Complex 1 crystallizes in the monoclinic system, space group P2/n with a = 10.420（1）, b = 19.485（1）, c = 11.079（1） A, β = 109.63（1）°, V= 21 1 8.8（1） A3, C40H34Mn4N4019, Mr = 1094.47, Dc= 1.715, Z = 2, F（000） = 1108,/2 = 1.251, R = 0.0300 and wR = 0.0812 for 4236 observed reflections （I 〉 2σ（/））. Single-crystal X-ray structure analysis reveals that 1 features a two-dimensional （3,6）-connected layer constructed by [Mn4（OH）2（H20）2]6＋ clusters. The adjacent layers are further linked with each other by hydrogen bonds to produce an unusual binodal （4,12）-connected 3D supramolecular network with 4-connected L3- ligands and 12-connected tetranuclear [Mn4（OH）2（H20）2]6＋ subunits.
