Abstract
The compound [Ni(bipy)3][NaAl(ox)3], where ox2– is the oxalate dianion and bipy is 2,2′-bipyridine, was obtained by mixing of K2[Ni(ox)2(H2O)2]·4H2O and [H2bipy]Cl2 in silica hydrogel at room temperature. The complex, which incorporates Na and Al from the silica gel, was characterised by Fourier-transform IR spectroscopy, energy-dispersive X-ray analysis, thermogravimetric techniques and single-crystal X-ray diffraction. It crystallises in the cubic system, space group P213, with a= 15.518(2)Å, U= 3736.9(8)Å3 and Z= 4. The crystal structure consists of a chiral, three-dimensional polymeric network of Al3+ and Na+ bridged by bis(bidentate oxalate) ligands, [NaAl(ox)3]n 2n–, with the [Ni(bipy)3]2+ cations inserted in the anionic network cavities. The cations and anionic network are held together by means of electrostatic forces and weak C–H ⋯ O hydrogen bonds.Keywords
