Er. Humphrey et al., AN UNPRECEDENTED TRINUCLEATING BRIDGING MODE (MU(3)-ETA(1)-ETA(1)-ETA(1)) OF A TRIS(PYRAZOLYL)BORATE LIGAND IN A TRINUCLEAR SILVER(I) COMPLEX, Journal of the Chemical Society. Dalton transactions (Print), (20), 1998, pp. 3353-3354
The crystal structure of [Ag-3(Tp(An))(2)][ClO4], where Tp(An) is tris
[3-(2-methoxyphenyl)pyrazol-1-yl]hydroborate, shows a unique trinuclea
ting bridging coordination mode for the tris(pyrazolyl)borate: each of
the two ligands coordinates one pyrazolyl donor to each of the three
two-coordinate Ag(I) ions, affording a triangular complex in which eac
h face is capped by a mu(3)-eta(1):eta(1):eta(1)-tris(pyrazolyl)borate
.
