Synthesis and Description of a Novel Metal‐organic Framework Based on Trigonal Prismatic Building Blocks

Abstract A novel metal‐organic framework based on trigonal prismatic building blocks has been hydrothermally prepared and structurally characterized. It crystallizes in the cubic space group Pa$\bar{3}$ with Z = 8. The oxo‐centered trinuclear complex units are bridged by 1,3‐benzenedicarboxylate (1,3‐BDC) ligands, forming a new 3D open‐framework [Fe3O(H2O)3(1,3‐BDC)3][Cl]·9H2O (1). Its magnetic behavior has been quantitively analyzed by the Bleaney–Bowers equation, indicating the presence of antiferromagnetic interactions within the trinuclear FeIII atoms.
