Synthesis and crystal structure of a new dysprosium(III) complex with 2-fluorobenzoato and 1,10-phenanthroline

The dysprosium complex with 2-fluorobenzoato (2-FBA) and 1,10-phenanthroline (phen) was synthesized and characterized by X-ray diffraction. The complex crystallizes in the triclinic system with space group , lattice parameters: a = 11.233(7)  Å, b = 12.598(8)  Å, c = 22.718(14)  Å, α = 81.045(13)°, β = 78.213(12)°, γ = 80.506(11)°, V = 3079(3) ų, Z= 2, Dcalc = 1.689 Mg/m³. The complex contains two independent binuclear molecules, namely, Dy(2-FBA)₃·phen·CH₃CH₂OH]₂ (I) and Dy(2-FBA)₃·phen]₂ (II). In molecule (I), Dy1³⁺ ion is coordinated by eight atoms, five O atoms from five 2-FBA groups, one O atom from an ethanol molecule and two N atoms from the phen ligand. The 2-FBA groups adopt monodentate and bridging two-coordination modes. In molecule (II), the Dy2³⁺ ion is coordinated by nine atoms, seven O atoms from five 2-FBA groups and two N atoms from the phen ligand. The 2-FBA groups adopt chelating, bridging and chelating-bridging three-coordination modes.Supplementary material CCDC-257186 for the compound contains the supplementary crystallographic data for this paper.
