Assembly of a Cubic Nanocage Co8L12 and a Hydrogen-Bonded 3D NbO Net Based on the [(HCO3)2]2− Synthon and Water
摘要:
Two new complexes [Co(H2O)(6)subset of Co-8(L1)(12)]X-6 center dot nH(2)O (X = NO3-, n = 12 (1); X = HCO3-, n = 24, (2); HL1 = 4,6-bis(2-pyridyl)-1,3,5-triazin-2-ol) have been synthesized and characterized by single-crystal X-ray diffraction. A [Co(H2O)(6)](2+) ion is encapsuled in the central cavity of the cubelike nanocage [Co(H2O)(6)subset of Co-8(L1)(12)](6+) cation, assembled by eight cobalt ions at the corners and twelve bis-bidentate ligands L1 as the edges, via the formation of 12-fold strong hydrogen bonds between the six coordinated water molecules and the oxygen atoms of twelve L1 as a guest. Complex 1 crystallizes in a centrosymmetric space group P1, while 2 is in a very high symmetric space group Im3. In 2, a planar [(HCO3)(2)](2-) dimer motif R-2(2)(8) synthon plus six lattice water molecules constitute a planar supramolecular synthon R(20), which acts as a four connector, generating a 3D hydrogen-bonded NbO net with cubelike host cavities of similar to 20 angstrom diameter. Interestingly, the cubelike nanocage [Co(H2O)(6)subset of Co-8(L1)(12)](6+) cations fill in the cavities as templates. The magnetic properties of 1 have also been studied in the temperature range of 2-300 K, and its magnetic susceptibility obeys the Curie-Weiss law, showing antiferromagnetic coupling.
