Synthesis, Crystal Structure and Magnetic Behaviour of {[Yb(1,4-BDC)(HO)]·HO} (1,4-BDC = 1,4-benzenedicarboxylate).

The title complex {[Yb(1,4-BDC)(HO)]·HO} (1) (1,4-BDC = 1,4-benzenedicarboxylate) has been hydrothermally synthesized and structurally characterized by the single crystal X-ray diffraction. Crystals of compound 1 belongs to the triclinic crystal system, space group P-1; a = 7.549(3) Å, b = 10.072(4) Å, c = 10.470(4) Å, α = 87.810(4)°, β = 82.531(4)°, γ = 86.306(4)°, V = 787.3(5) Å, Z = 2. The Yb(III) atoms are linked by the deprotonated 1,4-BDC ligands in two kinds of bridging modes. Four Yb(III) atoms at each corner (nodes) and four 1,4-BDC ligands at each edge (spacers) form a edge-sharing 36-membered rings. The rhombohedral Yb(1,4-BDC) arranged in an alternating fashion to construct a 1D ladder-like chain along the c axis. Two neighboring chains are linked to each other in a parallel fashion to construct 3D supramolecular structure by O-H···O hydrogen bonds and π- π stacking interactions. In addition, the properties of thermogravimetric analysis and magnetic behaviors of the complex have been also discussed. Graphical Abstract: 1,4-Benzenedicarboxylate-bridged Yb(III) coordination polymer {[Yb(1,4-BDC)(HO)]·HO} was hydrothermally synthesized and characterized structurally. Yb(III) center is linked to three Yb(III) ions via the three 1,4-BDC ligands to form a edge-sharing 36-membered rings. The rhombohedral Yb(1,4-BDC) arranged in an alternating fashion construct a 1D ladder-like chain along the c axis. Magnetic behaviors have been also discussed.[Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR]
