Copper(II) coordination polymers constructed from aromatic polycarboxylate and flexible triazole ligands with different spacer lengths: syntheses,structures, and properties
Abstract:{[Cu2(btm)2(Hbtc)(H2btc)2(H2O)]·9.5H2O}n (1), [Cu(bte)(H2btc)2]n (2) {[Cu(btp)(H2btc)2]·0.25H2O}n (3) (btm?=?bis(1,2,4-triazol-1-yl)methane, bte?=?bis(1,2,4-triazol-1-yl)ethane, btp?=?bis(1,2,4-triazol-1-yl)propane, H3btc?=?benzene-1, 3, 5-tricarboxylic acid) have been synthesized and structurally characterized. 1 features a 1-D double chain, which is interconnected by classical hydrogen-bonding (O–H?O) and ππ interactions to lead to a 3-D supramolecular architecture. 2 and 3 are both 1-D single chains, which are interconnected by ππ interactions to 2-D layer architectures. Elemental analysis, XRD, IR, TG and EPR spectra have been carried out and discussed.
Keywords:H3btc  Bis(1,2,4-triazol-1-yl)methane  Bis(1,2,4-triazol-1-yl)ethane  Bis(1,2,4-triazol-1-yl)propane  EPR spectra
