Group 14 Zintl ions ([E9]4-, where E= Ge, Sn) have been known to form exo-functionalizedderivatives [RE9]3- (R= alkyl or post transition metal group). Isolated [HSn9]3- cluster, analogous to the [HP7]2- ion, is the first example of the hydride functionalized group 14 Zintl ions. Furthermore, the [HSn9]3- ion reacts with [Ni(cod)2] to give the endohedral [Ni@HSn9]3- ion. [K(2,2,2-crypt)]+ salts of both [HSn9]3- and [Ni@HSn9]3- ions have been characterized by single crystal X-ray diffraction, 1H and 119Sn NMR spectroscopy. Subsequently, the [Ni@HSn9]3- ion reacts with [(arene)M(CO)3] complexes to form [Ni@Sn9M(CO)3]4- ions (M= Cr, Mo). These novel ions were isolated as crystalline [K(2,2,2-crypt)]+ salts and have been characterized by single crystal X-ray diffraction, 13C NMR, and FT-IR spectroscopy.
