Thirteen new compounds based on different calix[4] arene derivatives, namely, [Mn(H3L1)(2)(phen)(3)] (1), [Cd(H3L1)(2)(phen)(3)] (2), [Ni(H3L1)(2)(phen)(3)] (3), [Co(H3.33L1)(3)(phen)(3)] (4), [Co(H3L1)(2)(en)(3)]center dot 2H(2)O (5), [Zn-2(H3L1)(4)(en)(4)(imi-4)]center dot H2O (6), [Zn6Na6(L-2)(4)(OH)(2)(imi-4)(H2O)(4)]center dot 5H(2)O (7), [Zn6Na6(L-2)(4)(OH)(2)(tria-4)(H2O)(4)]center dot 5H(2)O (8), [Co4Na2(L-2)(2)(OH)(2)(H2O)(6)]center dot 7H(2)O (9), [Cu3Na2(L-2)(2)] (10), [Cu7Na4(L-3)(4)(OH)(2)(H2O)(5)]center dot 6H(2)O (11), [Zn2Na(L-3)(OH)(H2O)]center dot 2H(2)O (12) and [Pb4Na2(L-3)(2)(OH)(2)] (13), where H4L1 = calix[4]arene, H4L2 = tetra(carboxymethoxy) calix[4] arene, H4L3 = tetra(carboxymethoxy)(p-tert-butyl)calix[4]arene, phen = 1,10-phenathroline, en = ethylenediamine, imi-4 = 1,4-bis(1H-imidazol-1-yl)butane and tria-4 = 1,4-bis(1,2,4-triazole-1-yl) butane, have been synthesized under hydrothermal conditions. Compounds 1 and 2 are isomorphous. In compound 1, the [Mn(phen)(3)](2+) unit acts as a guest and was trapped in the dimeric capsule of two H3L1 anions. The edge-to-face C-H center dot center dot center dot pi interactions between the dimeric capsule hold the [Mn(phen)(3)](2+) unit and H3L1 anion together. Further, face-to-face pi-pi interactions link the capsules into a three-dimensional (3D) supramolecular architecture. Compounds 3, 4 and 6 show 0D discrete structures, which are further linked by C-H center dot center dot center dot pi interactions to form 3D supramolecular architectures, respectively. In compound 5, the [Co(en)(3)](2+) cations and H3L1 anions are linked together through intermolecular hydrogen-bonding interactions, resulting in a 3D supramolecular architecture. Compound 8 is isomorphous with 7. In compound 7, Zn(II) and Na(I) ions are held together by L-2 anions and imi-4 ligands to generate a 2D layer structure. Compounds 9 and 10 show chain structures, and the chains are linked through hydrogen bonds and C-H center dot center dot center dot pi interactions to generate 3D supramolecular architectures, respectively. Compound 11 displays a column structure. Adjacent columns are linked by the C-H center dot center dot center dot O and O-H center dot center dot center dot O interactions to give a 2D supramolecular layer. Compound 12 exhibits a 1D ribbon-like structure. Compound 13 possesses a dimeric structure. The dimers are extended by the C-H center dot center dot center dot O interactions into a 1D supramolecular chain. The powder X-ray diffraction and luminescent properties have also been studied for the compounds.
