Tetra­kis(μ-4-tert-butyl­benzoato)-κ(4) O:O′;κ(3) O,O′:O′;κ(3) O:O,O′-bis­[aqua­(4-tert-butyl­benzoato-κ(2) O,O′)(4-tert-butyl­benzoic acid-κO)neodymium(III)]

The reaction of neodymium nitrate and 4-tert-butyl­benzoic acid (tBBAH) in aqueous solution yielded the dinuclear title complex, [Nd(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 Nd(III) ions are linked by two bridging and two bridging–chelating tBBA ligands with an Nd⋯Nd separation of 4.0624 (5) Å. Moreover, each Nd(III) ion is coordinated by one chelating tBBA ion, one monodentate tBBAH ligand and one water mol­ecule. The nine-coordinated Nd(III) ion is in a distorted tricapped trigonal–prismatic environment. The mol­ecules are linked into infinite chains along the c axis by inter­molecular O—H⋯O hydrogen bonds. Three of the tert-butyl groups are disordered over two sets of sites with equal occupancies.
