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

摘要

The conversion of tin chloride reagents into the corresponding hydroxides typically results in the formation of oligomeric tin oxides.[1]-[3] We report herein the preparation and reactivity of a trinuclear nickel cluster that is capped by a 3-Sn(OH)3 group. This is a rare example of a complex that contains an intact trihydroxy tin group, thus allowing the study of the chemistry of tin hydroxides without interference from competing reactions that form oligomeric tin oxides.
