Triaqua(4-hydroxypyridine-2,6-dicarboxylato-κ<sup>3</sup><i>N,O,O</i>′)zinc(II)–acetonitrile–water(1/0.25/1)

H9a-Acr) 2 [Ni(hypydc) 2 ]•4H 2 O (1), (H9a-Acr) 2 [Co(hypydc) 2 ]•3H 2 O (2), (H9a-Acr) [Cr(hypydc) 2 ]•3H 2 O (3), and (H9a-Acr) 2 [Cd(hypydc) 2 ]•3H 2 O ( 4) compounds (H 2 hypydc = 2,6-dicarboxy-4-hydroxypyridine or chelidamic acid; 9a-Acr = 9-aminoacridine) were synthesized via proton transfer and characterised by elemental analysis, IR spectroscopy, and single crystal X-ray diffraction techniques. Thermogravimetric analysis (TGA) was carried out on compounds 1 and 2. Compounds 1-4 have distorted octahedral geometries with two hypydc 2− ions coordinated as tridentate ligands to each metal ion through one oxygen atom of each carboxylate group and the nitrogen atom of the pyridine ring. In the compounds, strong hydrogen bonds between anionic, cationic, and water fragments and especially the different natures of the π + ⋯π − and π − ⋯π − stacking interactions play important roles in the construction of threedimensional supramolecular frameworks which have been analysed in detail. The smaller trans N-M-N angle observed in 3 as compared with the others has been analysed using DFT calculations. Solution studies have also been performed to understand the behaviour of the ternary systems M n+ -H 2 hypydc-9a-Acr in aqueous solution.

In the title complex, [Cu(C7H3NO5)(C14H12N2)]·3H2O, there are two independent neutral molecules of the Cu complex along with six molecules of water of hydration in the asymmetric unit. The CuII atoms in each complex adopt a distorted square-pyramidal coordination geometry being pentacoordinated by one N and two O atoms of 4-hydroxypyridine-2,6-dicarboxylate anions and two N atoms of 2,9-dimethyl-1,10-phenanthroline (dmp) molecules. In the crystal structure, there are O—H⋯O and C—H⋯O hydrogen bonds and five π–π stacking interactions with centroid–centroid distances in the range 3.620 (1)–3.712 (1) Å. In addition, a C—H⋯π interaction between a heterocyclic ring of dmp is observed to reinforce the crystal cohesion.
