In the crystal structure of the title compound, 2C(10)H(7)NO(4)·C(14)H(13)N(3)O(2), the two independent acid mol-ecules are connected through strong O-H?N and O-H?O hydrogen bonds to the central mol-ecule of the anti-tubercular drug N’-[(E)-4-meth-oxy-benzyl-idene]pyridine-4-carbohydrazide. Two such trimolecular units related by an inversion centre inter-act through a pair of N-H?O hydrogen bonds, forming a 3 + 3 mol-ecular aggregate. The dihedral angle between the aromatic rings of the hydrazone mol-ecule is 1.99?(12)°. The crystal packing features weak C-H?O and ?-? stacking inter-actions, with centroid-centroid distances of 3.8460?(19) and 3.8703?(13)?Å.

The title compound, C(15)H(20)O(2), crystallizes with two independent mol-ecules of similar geometry in the asymmetric unit. The cyclo-hexyl ring adopts a chair conformation in each mol-ecule. In the crystal, mol-ecules related by translation are linked into chains along the a axis via weak C-H?O inter-actions.

The crystal structure of the polymeric title complex, [Zn(C(14)H(8)O(4))](n), is composed of layers parallel to (110) formed by linking of Zn-carboxyl-ate chains with biphenyl units of the biphenyl-2,4′-dicarboxyl-ate (bpdc) ligands. The Zn(II) atom is five-coordinated in a distorted square-pyramidal geometry by five O atoms from four bpdc ligands. The dihedral angle between the benzene rings is 52.32?(12)°.
