Crystal structure of catena poly[bis­­(tetra­ethyl­ammonium) [tetra­aqua­tris­(μ dicyanamido κ2N1:N5)bis­(dicyanamido κN1)di­cobaltate(II)] dicyanamide]

Weak C—H O hydrogen bonds are also present between the C—H groups of bridging pyrazine and coordinating acetonitrile molecules, and the oxygen atoms of nitrate ions, linking Co

An intricate network of O—H O and O—H N hydrogen bonds involving the carboxy group, the coordinating water molecules and the two types of solvent molecules leads to the

Two non-clas- sical hydrogen bonds were formed between the O atom from the –COOH or –OH groups of the HPA, and the H atoms from the imidazole rings of the two monomer molecules,
