摘要
The hydrothermal reaction of In(3+) and 1,2,4-benzenetricarboxylic acid with the presence of piperazine leads to the generation of a novel 3D porous coordination polymer, [H(3)O][In(2)(btc)(bdc)(OH)(2)]center dot 5.5H(2)O (1), (btc=1,2,4-benzenetricarboxylate, bdc=1,4-benzenedicarboxylate). Compound I crystallizes in orthorhombic space group Pbca with a=16.216(7) angstrom, b=13.437(6) angstrom, c=31.277(14) angstrom, and Z=8. It is interesting to find that the in-situ decarboxylation reaction of 1,2,4-benzenetricarboxylate (btc) partially transformed into 1,4-benzenedicarboxylate (bdc) Occurs. The 16 indium(III) centers were linked by four btc, four bdc and two mu(2)-OH ligands to form a box-girder. The adjacent box-girders are further connected by the bdc and btc ligands to generate a novel porous metal-organic framework containing nanotubular open channel with a cross-section of approximately 11.5 x 11.3 angstrom(2). The micropores are occupied by lattice water molecules, and the solvent-accessible volume of the unit cell was estimated to be 3658.6 angstrom(3), which is approximately 53.7% of the unit-cell volume (6815.4 angstrom(3)).
