The asymmetric unit of the title compound, 3C(10)H(8)N(2)·2C(7)H(7)NO(2), consists of three mol-ecules of 4,4'-bipyridine (bpy) and two mol-ecules of 3-amino-benzoic acid (bza). Two mol-ecules of bza and two mol-ecules of bpy are connected via O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds, forming forming infinite double-stranded zigzag chains along the c axis. The third mol-ecule of bpy is linked to the chain by weak C-H⋯O inter-actions. Adjacent chains are linked via π-π inter-actions [centroid-centroid distances = 3.759 (3)-3.928 (3) Å] involving the pyridine rings of bpy mol-ecules, resulting in a sheet-like structure parallel to (100). These sheets are stacked via C-H⋯π inter-actions, resulting finally in the formation of a three-dimensional supra-molecular structure.

The central copper(II) atom of the title salt, {[Cu(CFSO)(CHCN)(CHNO)](CFSO)} or [[Cu(CHCN)(diOMe-bpy)(CFSO)](CFSO)] where diOMe-bpy is 4,4'-dimeth-oxy-2,2'-bi-pyridine, CHNO, is sixfold coordin-ated by the N atoms of the chelating bi-pyridine ligand, the N atoms of two aceto-nitrile mol-ecules, and two tri-fluoro-methane-sulfonate O atoms in a tetra-gonally distorted octa-hedral shape. The formation of polymeric chains [Cu(CHCN)(diOMe-bpy)(CFSO)] leaves voids for the non-coordinating tri-fluoro-methane-sulfonate anions that inter-act with the complex through weak hydrogen bonds. The presence of weakly coordinating ligands like aceto-nitrile and tri-fluoro-methane-sulfonate makes the title compound a convenient starting material for the synthesis of novel metal-organic frameworks.

A one-dimensional nickel(II) coordination polymer with the mixed ligands 6-fluoro-nicotinate (6-Fnic) and 4,4'-bi-pyridine (4,4'-bpy), namely, -poly[[di-aqua-bis-(6-fluoro-pyridine-3-carboxyl-ato-κ)nickel(II)]-μ-4,4'-bi-pyri-dine-κ :'] trihydrate], {[Ni(6-Fnic)(4,4'-bpy)(HO)]·3HO} , (), was prepared by the reaction of nickel(II) sulfate hepta-hydrate, 6-fluoro-nicotinic acid (CHFNO) and 4,4'-bi-pyridine (CHN) in a mixture of water and ethanol. The nickel(II) ion in is octa-hedrally coordinated by the O atoms of two water mol-ecules, two O atoms from -monodentate 6-fluoro-nicotinate ligands and two N atoms from bridging 4,4'-bi-pyridine ligands, forming a isomer. The bridging 4,4'-bi-pyridine ligands connect symmetry-related nickel(II) ions into infinite one-dimensional polymeric chains running in the [10] direction.

In the title 1:2 co-crystal, CHN ·(CHO·CHO), l-ascorbic acid (LAA) and 4,4'-bi-pyridine (BPy) co-crystallize in the chiral space group 2 with two mol-ecules of LAA, and one mol-ecule of bpy in the asymmetric unit. The structure was modeled in two parts due to possible proton transfer from LAA to the corresponding side of the bpy mol-ecule having an occupancy of approximately 0.25 and part 2 with an occupancy of approximately 0.
