Hydride-encapsulated bimetallic clusters supported by 1,1-dithiolates†
Abstract
Two mixed-metal hydride clusters, corresponding to x = 3 and 4, were structurally characterized from a set of atomically precise heptanuclear clusters, CuxAg7−x(H){S2P(OiPr)2}6 (x = 1–6). An interstitial hydride lying at the center of a tricapped tetrahedral cage was located and refined anisotropically by using X-ray data, and its presence acertained by multinuclear NMR spectroscopy and DFT calculations.
