Abstract: The solvothermal reaction of nickel^II acetate with H₃BTC (benzene-1,3,5-tricarboxylic acid) in water gave the title complex, [Ni₃(C₉H₃O₆)₂(H₂O)₈]_n. Single-crystal X-ray analysis shows that the structure contains four crystallographically unique Ni atoms. Two of these each lie at a center of symmetry and each is coordinated by two water molecules and four O atoms from four carboxylate groups. The other two are each coordinated by four water molecules and two O atoms from two carboxylate groups. The different types of chemically unique Ni atoms are connected by ₂-H₂O and carboxylate groups of BTC ligands to form two two-dimensional networks. The hydrogen-bonding interactions between the layers further connected these two-dimensional layers into a three-dimensional frame work in a parallel fashion.
