Calcium complex of 2,5-dihydroxybenzoic acid (gentisic acid): synthesis, crystal structure, and spectroscopic properties

“…There are many studies on structures and functions of alkaline earth complexes with amino- [8,9], nitro- [2,6,7,10], hydroxybenzoic [4,11], and benzoic [12] acids. strong metal-ligand bonding and weaker bonding forces such as hydrogen bonding and π-π interactions stabilize the structures of these compounds.…”

“…A total of 44% of all studied structures revealed coordination number of eight. In the majority of cases, calcium complexes prepared in aqueous media contain up to four coordinated water molecules [4,10,12,18]. There are only a few calcium compounds with higher number of water molecules, for example: (ImH) 4 11 ]·5H 2 O (CMP = cytidine 5′-monophosphate) [22].…”
