Abstract
We present a barium metal-organic framework {[Ba(in)(H2O) 6][in]}∞ prepared via a simple acid-base reaction between BaCO3 and inH (inH = 4-pyridinecarboxylic acid). The complex crystallizes in the monoclinic space group P21/c (a = 6.2592(18), b = 44.289(12), c = 7.2754(15); α=γ= 90, β= 118.890(18); V = 1765.8(8)Å3) displaying an unusual ion association mode with half of the anions metal-bound, whereas the others are associated via a hydrogen-bonded and π⋯π stacking network. Among the coordinated anions, the carboxylate functionalities bridge the metal centers.
