Three new 2D metal-organic frameworks, [M(BIDPE)2(bdc)2]n(M = Co for 1, Ni for 2) and [Ni(PIDPE)2(H2O)2(bdc)]n(3)(BIDPE = 4,4?-bis(imidazol-1-yl) diphenyl ether, PIDPE =4-(pyridyl)-4?-(imidazol-1-yl) diphenyl ether, bdc2- = 1,3-benzenedicarboxylate), were characterized by single-crystal X-ray diffraction, elemental analysis, PXRD, IR spectroscopy and TGA analysis.Complex 1 crystallizes in monoclinic, space group P21/n, with a = 9.1568(12), b = 16.943(2), c =15.441(2) ?, β = 104.049(2)°, V = 2323.9(5) ?~3, Dc = 1.420 g/cm~3, Mr = 993.83, F(000) = 1026, μ =0.440 mm~(-1) and Z = 2. Complex 2 crystallizes in monoclinic, space group P21/n, with a =9.1395(17), b = 17.019(3), c = 15.473(3) ?, β = 104.651(2)°, V = 2328.5(7) ?~3, Dc = 1.414 g/cm~3,Mr = 991.58, F(000) = 1024, μ = 0.487 mm-1, Z = 2. Complex 3 also belongs to the monoclinic system, space group P21/n, with a = 11.4365(16), b = 18.346(3), c = 11.7068(17) ?, β = 91.022(2)°,V = 2455.9(6) ?3, Dc = 1.422 g/cm3, Mr = 1051.66, F(000) = 1092, μ = 0.468 mm-1, Z = 2. All complexes 1, 2 and 3 are 2D layer structures constructed from intermolecular hydrogen bonds. In addition, the solid UV-vis properties of complexes 1, 2 and 3 were also studied.
