The reaction of [CuI(HSC 6 H 4 PPh 2 )] 2 with NaBH 4 in CH 2 Cl 2 /EtOH led to air‐ and moisture‐stable copper hydride nanoparticles (CuNPs) containing phosphinothiolates as new ligands, one of which was isolated by crystallization. The X‐ray crystal structure of [Cu 18 H 7 L 10 I] (L= − S(C 6 H 4 )PPh 2 ) shows unprecedented features in its 28‐atom framework (18 Cu and 10 S atoms). Seven hydrogen atoms, in hydride form, are needed for charge balance and were located by density functional theory methods. H 2 was released from the copper hydride nanoparticles by thermolysis and visible light irradiation.
