Thiacalix[3]pyridine produces a stable mononuclear rhodium(II) complex with mutual Jahn-Teller effect.

Thiacalix[3]pyridine (Py3S3) consists of pyridines and bridging sulfur atoms producing a stable octahedral mononuclear Rh(II) complex [Rh(II)(Py3S3)2]2+ showing mutual Jahn-Teller effect, a metal based reversible redox couple of Rh(III/II) at 0.02 V vs. SCE and a g(perpendicular) > g(||) relationship in EPR measurements.

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.
