Abstract: In the title complex, [CdCl₂(C₁₅H₁₃N₅)] or [CdCl₂(tpdaH₂)] (tpdaH₂ is tripyridyldiamine), the geometry at the five-coordinate Cd atom is distorted tetragonal pyramidal, with two Cl atoms and the three pyridine N atoms of the tripyridyldiamine molecule. The ligand (tpdaH₂) adopts an all-anti form. The observed Cd-N bond lengths are 2.2958 (19), 2.3254 (19) and 2.3067 (19) Å, slightly shorter than those in the Cd²⁺ complex with di-2-pyridylamine (dpa).
