Poly[[chlorido­(1,10-phenanthroline-[kappa]²N,N')copper(II)]-[mu]₃-1,1,3,3-tetra­cyano-2-eth­oxy­propenido-[kappa]³N:N':N'']: coordination polymer sheets linked into bilayers by hydrogen bonds

In the title complex, the (4 + 2) coordination polyhedron around the Cu^II centre includes N atoms from three different 1,1,3,3-tetra­cyano-2-eth­oxy­propenide ligands, so forming a two-dimensional coordination polymer.

1,1'-Diethyl-4,4'-bi­pyridine-1,1'-di­ium bis­(1,1,3,3-tetra­cyano-2-eth­oxy­pro­penide): multiple C-H...N hydrogen bonds form a complex sheet structure

A bipyridinediium propenide salt forms complex hydrogen-bonded sheets in which each cation acts as a sixfold donor of C-H...N hydrogen bonds and each anion acts as a threefold acceptor.

In a one-dimensional coordination polymer containing approximately square-pyramidal Cu^II, with one bridging and one terminal dicyanamide ligand, the polymer chains are linked by hydrogen bonds and [pi]-[pi] stacking inter­actions.

Tris(2,2′-bi­pyridine)­iron(II) bis­(1,1,3,3-tetra­cyano-2-eth­oxy­propenide) dihydrate: chiral hydrogen-bonded frameworks inter­penetrate in three dimensions

Multiple hydrogen bonds in tris­(2,2′-bi­pyridine)­iron(II) bis­(1,1,3,3-tetra­cyano-2-eth­oxy­propenide) link water mol­ecules, anions and chiral cations into two inter­penetrating chiral frameworks.

Coordination polymer chains built from Cu^II and adipate ions linked by hydrogen bonds to form a three-dimensional framework structure

Coordination polymer chains built from Cu^II and adipate ions are linked into a framework structure by hydrogen bonds and [pi]-[pi] stacking inter­actions involving 2,2'-bi­pyridine and 1,1,3,3-tetra­cyano-2-eth­oxy­propenide components.
