Abstract The synthesis and crystal structure of sodium hydrogen dipicolinate dipicolinic acid trihydrate, NaHdipic · H2dipic · 3H2O,I, is reported. There is a hydrogen bonded H3(dipic)2 − unit in which an Hdipic− ion functions as a tridentate chelate to the Na+ ion while the second H2dipic functions as a monodentate ligand and bridging unit. The Na+ ion is in the center of a pentagonal bipyramid with two water molecules in the axial positions. The equatorial plane is composed of an Hdipic− ion, a water molecule and an oxygen from the H2dipic. An analysis of data in the Cambridge Structural Database for Na+ compounds using Valence Bond Sums has produced newr 0 values of 1.743 for Na−O and 1.891 for Na−N.
