Bis[μ‐N,N′‐bis(quinolin‐8‐yl)pyridine‐2,6‐dicarboxamido]dizinc(II) dichloromethane disolvate

The title compound, Zn₂(C₂₅H₁₅N₅O₂)₂]·2CH₂Cl₂, is a dinuclear double‐helical complex which lies on a crystallographic twofold axis. In the complex, both ligands are partitioned into two tridentate domains which allow each ligand to bridge both metal centres. Each Zn^II atom is six‐coordinated in a distorted octahedral environment formed by two amide N atoms, two quinoline N atoms and two pyridine N atoms from two different ligand molecules, with the central pyridine ring, unusually, bridging two Zn^II atoms. The deprotonated ligand is not planar, the amide side chains being considerably twisted out from the plane of the central pyridine ring.
