“…Up to now, several transitionmetal complexes based on chelidamic acid have been documented, many of them containing lanthanide metals. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] At the initiation of this work, to the best of our knowledge, no proton transfer studies and complexes using this ligand with 9-aminoacridine had been reported (however as the study was being completed, three such complexes were reported, one of which is identical with the nickel complex prepared here). 20 Therefore, we selected chelidamic acid as the major ligand and 9-aminoacridine as an auxiliary (see Scheme 1) ligand for testing their reactions with some transition metal salts.…”

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.

Four new complexes of chelidamic acid (H3cda) in the presence\ud of 2-aminopyrimidine (apym) or 2,4,6-triamino-1,3,5-triazine\ud (tata) as external ligands, namely (apymH)[VO2(Hcda)]·H2O (1),\ud [Ni(Hcda)(apym)(H2O)2]·H2O (2), (apymH)[Fe(Hcda)2] (3), and (tataH)\ud 2(tata)2[Ca2(cda)2(H2O)6]·H2O (4) were synthesized. X-ray diffraction\ud analysis of 1-4 revealed the formation of 3D frameworks\ud generally involving weak interactions (mainly H-bonds)\ud between metal complexes of chelidamic acid, protonated or\ud deprotonated external ligands apym or tata and co-crystallized\ud water molecules. Some complexes present remarkable assemblies\ud in the solid state governed by unconventional noncovalent\ud interactions that have been analyzed by means of DFT\ud calculations. Solution studies were also performed to fully characterize\ud the new compounds
