A Host-Guest Supercapacitor Electrode Material Based on a Mixed Hexa-Transition Metal Sandwiched Arsenotungstate Chain and Three-Dimensional Supramolecular Metal-Organic Networks with One-Dimensional Cavities.

The mixed hexa-transition metal (hexa-TM) sandwiched arsenotungstate derivative, [Cu(pz)(phen)][Cu(phen)][{Na(HO)}{(VCuO)(AsWO)}]·6HO (1) (pz = pyrazine; phen = 1,10-phenanthroline), has been hydrothermally synthesized and structurally characterized. In compound 1, two {AsWO} clusters are connected by mixed hexa-TM ring unit {VCuO} to form a sandwich-type dimer, which are further bonded in "ABAB" mode by the {Na(HO)} linker resulting in pure inorganic chains. The unique "L-shaped" trinuclear complex {Cu(phen)(pz)} is supported together via staggered π-π interactions to generate extending waveform two-dimensional supramolecular layers, which are further aggregated with their adjacent analogues by complexes {Cu(phen)} via H-bonding interaction to yield an unprecedented three-dimensional (3D) metal-organic networks with one-dimensional (1D) cavities.
