Mimicking the photosynthetic system with strong hydrogen bonds to promote proton electron concerted reactions.

A Copper(2+) complex with a Cu(II)-C bond containing sp(3) configuration was used to investigate the role of strong hydrogen bonds in proton coupled electron transfer (PCET) reactions. The only example of a Cu(II)-C system realized so far is that using tris-(pyridylthio)methyl (tptm) as a tetradentate tripodal ligand. Using this ligand, [CuF(tptm)] and [Cu(tptm)(OH)] have been prepared.

A complete series of copper(II) halide complexes (X = F, Cl, Br, I) with a novel Cu(II)-C(sp3) bond.

A complete series of copper(ii) halide complexes [CuX(tptm)](X = F (), Cl (), Br (), I (); tptm = tris(2-pyridylthio)methyl) with a novel Cu(II)-C(sp(3)) bond has been prepared by the reactions of [Cu(tptm)(CH(3)CN)]PF(6)(.PF(6)) with corresponding halide sources of KF or n-Bu(4)NX (X = Cl, Br, I), and the trigonal bipyramidal structures have been confirmed by X-ray crystallography and/or EPR spectroscopy. The iodide complex easily liberates the iodide anion in acetonitrile forming the acetonitrile complex as a result.

A two-dimensional clathrate hydrate sandwiched by planar arrays of a copper complex.

The first structurally characterised example of a 2-D clathrate hydrate spontaneously assembles when [CuF(tptm)] (tptm = tris(2-pyridylthio)methyl) crystallises from toluene/water solutions to produce a material in which planar arrays of [CuF(tptm)] sandwich and hydrogen bond to continuous 2-D sheets of water that incorporate toluene molecules at regular intervals.
