| Popis: | A unique three-dimensional (3D) supramolecular compound, [Co(dpe)(BTC)(H2O)][Co(dpe)(BTC)(H2O)3][Co(dpe)(HBTC)(H2O)][Co(dpe)2(H2O)3.5(EtOH)0.5]·1.5H2O (1; dpe = 1,2-bis(4-pyridyl)ethane and H3BTC = benzenetricarboxylic acid), has been synthesized and structurally characterized by the single-crystal X-ray diffraction method. Compound 1 consists of four coordination polymers (CPs), two are two-dimensional (2D) layered metal–organic frameworks (MOFs) with (4,4) topology of [Co(dpe)(BTC)(H2O)]− and [Co(dpe)(HBTC)(H2O)], whereas the other two are one-dimensional (1D) polymeric chains of [Co(dpe)(BTC)(H2O)3]− and [Co(dpe)(H2O)3.5(EtOH)0.5]2+. The 3D supramolecular architecture of 1 is constructed via the penetration of interdigitated double-layered 2D rectangular-grid frameworks by two 1D coordination polymeric chains and entangled tightly by the subtle combination of intermolecular hydrogen bonding and π–π interactions among the four CPs. Controlled heating of the as-synthesized crystal 1 at ∼160 °C produces a... |
