A Trihydroxy Tin Group That Resists Oligomerization in the Trinuclear Nickel Cluster [Ni₃(μ‐P,P′‐PPh₂CH₂PPh₂)₃(μ₃‐L)‐ (μ₃‐Sn(OH)₃)]

Abstract

Tin caps: A straightforward synthetic pathway leads to a series of trihydroxy tin capped trinuclear nickel clusters. The Sn(OH)3 groups of the clusters resist oligomerization. They display high nucleophilicity leading to reversible formation of an η2-carbonato tin capped cluster in the presence of CO2 (see scheme) and ring opening of 1,2-epoxybutane to the corresponding tin coordinated diolate.
