In the context of the intensely investigated field of heterometal doping of coinage nanoclusters (NCs), an increasing attention has shifted toward NCs doped with first-row transition metals due to their economic viability. Herein, the Ni-Ag bimetallic NCs [NiAg20{S2P(OiPr)2}12] NiAg20 and [NiHAg19{S2P(OiPr)2}12] NiHAg19 are reported, which are synthesized via a one-pot reduction method. NiHAg19 is the first example of an NC containing an encapsulated NiH unit and a rare species exhibiting Ni(0)─H bonding. The NiAg20 and NiHAg19 compositions are confirmed by single-crystal X-ray diffraction (SCXRD) and supported by density functional theory (DFT) calculations. Both NCs feature a superatomic 8-electron count with 1S21P6 configuration. The effect of nickel-doping on the oxygen evolution reaction (OER) catalytic performance is investigated. It significantly enhances alkaline OER activity, with NiAg20 and NiHAg19 showing improved catalytic performances compared to their monometallic silver counterparts.

01:08Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...

Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....
