The title complex was synthesized and its structure was determined. The crystal is monoclinic with space group P 2 1 / n . Unit cell parameters are as follows: a =16.474(8), b =12.425(4), c =20.844(12)Å, β=109.27(4)°, Z =4. In each dimer, the two Nd atoms are connected through two pairs of bridging neopentanoate anions. The two carboxyl groups in each pair are in opposite position to Nd atom which are coplanar with them and the two planes are perpendicular with each other. In the complex each Nd atom is further coordinated with three neopentanoic acid molecules and one monodentate neopentanoate anion. The central atom is octa‐coordinated in a square‐antiprism arrangement.
