چکیده
In the title compound, C(13)H(9)NO(4), the two carb-oxy-lic groups and the benzene ring are approximately co-planar with a maximum atomic deviation 0.175 (4) Å, while the pyridine ring is oriented at a dihedral angle of 31.07 (18)° with respect to the benzene ring. In the crystal, mol-ecules are linked by O-H⋯O, O-H⋯N and weak C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular framework.

In the crystal structure of the title co-crystal, C25H32N4O2·C8H6O4, isophthalic acid and [propane-1,3-diylbis(piperidine-4,1-di-yl)]bis-(pyridin-4-yl-methanone) mol-ecules are connected into supra-molecular chains aligned along the c axis by O-H⋯N hydrogen bonding. These aggregate into supra-molecular layers oriented parallel to the ac plane by C-H⋯O inter-actions. These layers then stack in a...

The title compound, C(12)H(8)N(4)O(2)·C(8)H(6)O(4), was synthesized from 4-[5-(4-pyrid-yl)-1,3,4-oxadiazol-2-yl]pyridine N-oxide and isophthalic acid. The two mol-ecules are linked through O-H⋯O and O-H⋯N hydrogen bonds. Weak intra-molecular π-π inter-actions between the two hydrogen-bonded chains result in the formation a one-dimensional supra-molecular curved tape (the face-to-face distance b...

In the title compound, {[Nd(C(14)H(9)N(2)O(5))(C(14)H(8)N(2)O(5))]·2H(2)O}(n), the Nd(III) atom is eight-coordinated as it is surrounded by eight carboxyl-ate O atoms from six ligands in a distorted square-anti-prismatic arrangement. The Nd(III) atoms are linked by HL(-) and L(2-) ligands [H(2)L is 5-(pyridine-4-carboxamido)-isophthalic acid], forming a bilayer network. The layers are linked in...

In the title 1:1 co-crystal, C12H10N2·C8H7NO4, the bi-pyridine moiety shows whole-mol-ecule disorder over two sets of sites in a 0.588 (3): 0.412 (3) ratio. In the crystal, the components form hydrogen-bonded sheets linked by N-H⋯O and O-H⋯N inter-actions, which stack along the a axis. A comparison to a related and previously published co-crystal of 5-amino-isophthalic acid and the shorter 4,4'...
