Pyridinium tetra­kis­(1,1,1-trifluoro­pentane-2,4-dionato)dysprosate

In the anion of the title compound, (C(5)H(6)N)[Dy(C(5)H(4)F(3)O(2))(4)], the central metal ion, Dy(3+), is coordinated by four bidentate 1,1,1-trifluoro­pentane-2,4-dionate (TAA) ligands, forming an approximate square-anti­prismatic configuration. The pyridin­ium cation is connected to the complex...

Sumario:In the anion of the title compound, (C(5)H(6)N)[Dy(C(5)H(4)F(3)O(2))(4)], the central metal ion, Dy(3+), is coordinated by four bidentate 1,1,1-trifluoro­pentane-2,4-dionate (TAA) ligands, forming an approximate square-anti­prismatic configuration. The pyridin­ium cation is connected to the complex ion by an N—H⋯O hydrogen bond and electrostatic inter­actions in the crystal. There are two kinds of disorder in the structure, one involving rotational disorder of a CF(3) group [occupancy ratio 0.560 (15):0.440 (15)] and the other involving an exchange between a CF(3) group and CH(3) group within a given bidentate ligand (occupancy ratio 0.64:0.36).
