Construction of Two New Metal–Organic Frameworks Based on Eight-Nuclear or 1D Rod-Shaped Secondary Building Units

Abstract

Two new metal–organic frameworks (MOFs), namely [Zn2(L) (bpy)0.5(OH)]∞ (1) and {[Ni2(L)(bpy)(OH)(H2O)]·2H2O}∞ (2) (L = biphenyl-3,3′,5-tricarboxylate and bpy = 4,4′-bipyridine), have been prepared and structurally characterized. In 1, the eight-nuclear Zn8(μ2-OH)4(COO)12 secondary building units (SBUs) are linked by neighboring ones through L and bpy ligands to result in a (3,16)-connected three-dimensional (3D) network with the point symbol of (424.544.640.78.84)(43)4. Complex 2 is constructed from Ni–O–C 1D rod-shaped SBUs and organic linkers to lead to the formation of a (3,4)-connected 3D network with the point symbol of (42.6.83)2(83).
