The structure of the centrosymmetric title complex, [Cu(C(5)H(9)O(2))(2)(C(6)H(7)NO)(2)], has the Cu(II) atom on a centre of inversion. The Cu(II) atom is six-coordinate with a distorted octa-hedral geometry, defined by the N and O atoms of the chelating 2-(2-hydroxymethyl)pyridine ligands and two carboxyl-ate O atoms from two monodentate pivalate ions. The crystal packing is stabilized by inter-molecular C-H⋯O and intra-molecular O-H⋯O hydrogen-bond inter-actions.

中心对称的标题配合物[Cu(C₅H₉O₂)₂(C₆H₇NO)₂]的结构中，Cu(II)原子位于对称中心。Cu(II)原子为六配位，具有扭曲的八面体几何构型，由螯合的2-(2-羟甲基)吡啶配体的N和O原子以及来自两个单齿新戊酸根离子的两个羧酸根O原子所定义。晶体堆积通过分子间C-H⋯O和分子内O-H⋯O氢键相互作用得以稳定。
