Self-assembly of transition metal salts with long aromatic dicarboxylate ligands and N-containing ligands affords a series of entangled coordination frameworks based on different metal cores, namely [Mn₄(μ₂-OH₂)₂(sdba)₄(bpp)₄] (1), [Mn₂(sdba)₂(btb)_0.5(H₂O)] (2), [Mn₄(sdba)₄(bim)(H₂O)₄]·2H₂O (3), [Ni(sdba)(bim)(H₂O)₂]·2H₂O (4), [Co₃(sdba)₂(Hsdba)₂(2,2′-bpy)₂] (5) and [Ni₂(bpda)₂(bim)₂]·H₂O (6) (H₂sdba = 4,4′-sulfonyldibenzoic acid, H₂bpda = 4,4′-carbonyldibenzoic acid, bpp = 1,3-bis(4-pyridyl)propane, btb = 1,4-bis(1,2,4-triazol-1-yl)butane, bim = 1,4-bis(imidazol-1-yl)butane, 2,2′-bpy = 2,2′-bipyridine). Their structures were determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, IR spectra and TG analyses. Compound 1 is a peculiar 2D self-threading network containing unusual triflexural helical motifs, which can be rationalized as a 6-connected 2D 3⁶-hxl (hexagonal lattice) net with double edges. Compound 2 represents the first example of a 2D polycatenated framework formed by 1D quadruple chains, which could be considered as formed by interconnected 1D polyrotaxane columns involving the unusual [3]rotaxane components. Compound 3 consists of two interlocked 2D cage-containing frameworks and exhibits an unusual (2D → 2D) parallel interpenetrating array with coexistence of polyrotaxane and polycatenane. Compound 4 is composed of two interpenetrating 2D loop-containing frameworks with 4-connected (2.6⁵) topology, and it can also be considered as being constructed by interconnected parallel 1D polyrotaxane chains. Compound 5 is comprised of two identical 2D hydrogen-bonded layers with 6-connected (2².4⁸.6⁵) topology that are interpenetrated in a parallel fashion, resulting in a twofold interpenetrating net having both polyrotaxane and polycatenane characters. Compound 6 represents an unusual mode of interpenetration of two distinct 3D frames both with CdSO₄ topology, which is still very rare in entangled systems. In addition, the magnetic properties of compounds 1, 3, 4, 5 and 6 are discussed.
