Synthesis and characterization of the triangulo raft cluster [(AgCo{CN(2,6-C6H3Me2)}4)3], a bimetallic hexanuclear isonitrile cluster

Six-, Five-, and Four-Coordinate Ruthenium(II) Hydride Complexes Supported by N-Heterocyclic Carbene Ligands: Synthesis, Characterization, Fundamental Reactivity, and Catalytic Hydrogenation of Olefins, Aldehydes, and Ketones

“…Likewise, the Ru1−C43−N5 bond angle is 172(2)° with the isonitrile bent away from the mesityl ring of the C22−NHC ligand into an open pocket. The bending of the isonitrile ligands are within the range observed for other isonitrile ligands, which readily distort as a consequence of packing interactions. , Yu et al have recently discussed the softness of the bending modes of the tert -butyl isonitrile ligand . Hence, it is plausible to surmise that these ligands will readily distort as a consequence of packing interactions.…”

Hexa- and Octanuclear Heterometallic Clusters with Copper–, Silver–, or Gold–Molybdenum Bonds and d10–d10 Interactions

“…Some heterometallic clusters with a central copper, silver, or gold triangle displaying d 10 –d 10 separations consistent with significant metallophilic interactions have been structurally characterized and include [M­{m}] 3 clusters with a ν 2 -triangular metal core (M = Cu, m = Fe and Os; M = Ag, m = Nb, Ta, Co, and Rh; M = Au, m = Nb) . Even fewer octanuclear heterometallic clusters [M­{m}] 4 with a central M 4 square or rectangle formed by group 11 metals separated by less than 3.4 Å have been characterized, and their edge-bridging metalloligands {m} form an external square (or rectangle) circumscribing the inner one, thus generating more or less distorted square-in-a-square-type structures .…”
