title: Tetra-kis(μ-4-tert-butyl-benzoato)-κO:O,O';κO,O':O';κO:O'-bis-[aqua-bis-(4-tert-butyl-benzoato-κO,O')(4-tert-butyl-benzoic acid-κO)praseodymium(III)].
abstract: The reaction of praseodymium nitrate and 4-tert-butyl-benzoic acid (tBBAH) in aqueous solution yielded the dinuclear title complex, [Pr(2)(C(11)H(13)O(2))(6)(C(11)H(14)O(2))(2)(H(2)O)(2)], which has non-crystallographic C(i) 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 mol-ecule in a distorted tricapped trigonal-prismatic environment. The complex mol-ecules are linked into infinite chains along the c axis by inter-molecular O-H⋯O hydrogen bonds.
