Metal complexes synthesis and properties

The title structure, Na 2 [Co(H 2 O) 6 ](C 10 H 4 O 8 ) 2 .4H 2 O, consists of [Co(H 2 O) 6 ] 2+ and Na + cations, dihydrogen 1,2,4,5-benzenetetracarboxylate(2-) (H 2 btc) anions and water of crystallization. The [Co(H 2 O) 6 ] 2+ and H 2 btc ions, as well as the water molecules, are linked together by a three-dimensional network of hydrogen bonds. A short symmetrical intramolecular hydrogen bond between the COO and COOH groups is found to exist in the H 2 btc ions.
