Tetra­kis(μ-4-tert-butyl­benzoato)-κ3 O:OO′;κ3 OO′:O′;κ4 O:O′-bis­aqua­bis­(4-tert-butyl­benzoato-κ2 OO′)(4-tert-butyl­benzoic acid-κO)praseodymium(III)

摘要

The reaction of praseodymium nitrate and 4-tert-butyl­benzoic acid (tBBAH) in aqueous solution yielded the dinuclear title complex, [Pr2(C11H13O2)6(C11H14O2)2(H2O)2], which has non-crystallographic Ci symmetry. The two Pr^III ions are linked by two bridging and two bridging–chelating tBBA ligands, with a Pr⋯Pr separation of 4.0817 (9) Å. Each Pr^III ion is nine-coordinated by one chelating tBBA ion, one monodentate tBBAH ligand and one water mol­ecule in a distorted tricapped trigonal–prismatic environment. The complex mol­ecules are linked into infinite chains along the c axis by inter­molecular O—H⋯O hydrogen bonds.
