The interaction between two porphyrin macrocycles, connected covalently through either a rigid ethylene or a flexible ethane bridge, in the metalloporphyrin dimers (M: 2H, Zn2+) have been investigated upon stepwise oxidations. Upon 1e-oxidation, two ...
2e-oxidation of ethylene-bridged metalloporphyrin dimers (M: 2H, Zn2+) result in the formation of dication diradical complexes in which the cis isomer converts to the trans isomer. Structural and spectroscopic investigations have revealed strong electronic communications between two porphyrin π-cation radicals through the bridge which also allows strong antiferromagnetic coupling between the radical spins to form diamagnetic complexes.

Experiments have indicated that bulky ligands are required for efficient H2 activation by Pt–Sn complexes. Herein, we unravel the mechanisms for a Pt–Sn complex, Pt(SntBu3)2(CNtBu)2 (1a), catalyzed reversible H2 activation. Among a number of Pt–Sn ...
Strain imposed on square-planar Pt(II) complexes by bulky ligands like −Sn(tBu)3 and −CN(tBu) facilitate H2 activation due to minimal structural reorganization.
