Anionic silver(I) complexes with closo-dodecaborate anion

Silver and Copper Complexes with closo-Polyhedral Borane, Carborane and Metallacarborane Anions: Synthesis and X-ray Structure

“…The binary copper(I) and silver(I) salts of closo-dodecaborate anion M2[B12H12] (M = Cu, Ag) were prepared [20,52,53]. Their X-ray structures were not determined, however the existence of M-H-B interactions in the solid state was supported by the IR spectroscopy data.…”

“…The centrosymmetric A1 anion provides linearity of the chain fragments of the chain, whereas the A2 anion provides a bend of the silver anionic chain (Figure 32) [53]. (6) Figure 30, the A1 anion) and one additional fragment, in which silver atom is coordinated by two closo-dodecaborate anions and an acetonitrile molecule.…”

“…(6) Figure 30, the A1 anion) and one additional fragment, in which silver atom is coordinated by two closo-dodecaborate anions and an acetonitrile molecule. Thus, the environment of silver Ag(1) and Ag (2) is formed by two edges of two symmetrically unequivalent icosahedra (A3 and A4) ( Figure 34) [53].

In the [(Ph 3 P) 2 Au] + cation the gold atom has a nearly linear coordination (Au-P bond lengths are 2.338(2) and 2.341(2) Å, P-Au-P angle is 170.91(7)˝) ( Figure 36) [56].…”

Exploring Ag⋯H–B interactions in coordination polymers: silver–alkanedinitrile networks with cobalt carbaborane anions

“…Although they are considered to be weakly coordinating anions, carbaborane compounds may be involved in agostic interactions with diverse metal centres. [30][31][32][33][34][35][36][37][38][39][40] In a recent study we reported a series of coordination complexes (either discrete, 1D or 3D polymers) of Ag(I) and smaller alkane dinitriles…”
