Hexakis[μ‐9‐methyl‐3‐(1H‐tetra­zol‐5‐io)‐4H‐pyrido[1,2‐a]pyrimidin‐4‐onato(2–)]tricadmium(II)

The centrosymmetric mol­ecule of the title CdII complex, [Cd3(C10H7N6O)6], is located on a threefold axis. The pyridopyrimidine ligands bridge neighbouring Cd atoms, forming a trinuclear complex. π–π Stacking is observed between neighbouring complex mol­ecules.
