Abstract

A self-assembled M₆L₈ type cage-connected 1D-coordination network of formula {[Ni₆(MeSi(³py)₃)₈Cl₉(H₂O)₂]Cl₃·16H₂O}_∞ (1) was obtained from a 3-pyridyl substituted silane ligand MeSi(³py)₃. This complex shows significantly high performance for the electrocatalytic and photocatalytic hydrogen evolution reaction (HER) in water. A maximum turnover number (TON) of 2824 has been observed for photocatalytic HER after 69 h.
