Unusual luminescent octanuclear stellate platinacycle self-assembled by Pt-Ag bonds.
An unprecedented macrocyclic luminescent octanuclear cluster cyclo-[{Pt(C6Cl5)2(mu-OH)(mu-Ag)}4] (Pt-Ag) 2 was self-assembled by the formation of Pt(II)-Ag(I) bonds; the optical properties of this complex were also investigated.

Theory of the d10−d10 Closed-Shell Attraction. 4. X(AuL)nm+ Centered Systems
The title species with the central atoms C, N, O, P, and S and up to six −AuPH3 ligands were studied at the MP2 level using effective core potentials. Structural parameters of the experimental systems were reproduced well. Two different ways of estimating the intramolecular gold−gold interaction energy from the calculated total energies are proposed, and the calculated interaction energies are found to correlate with the gold−gold distances in the systems. A giant proton binding energy of 1213 kJ/mol is calculated for the C4v species [HC(AuPH3)4]+.
