A core–shell type alkyl-Sn-oxo cluster of {Sn14As16} bridged by 4-aminophenylarsonate ligands and incorporated with a {Na6} cluster.

Herein, we report the largest organotin-oxo arsonate cluster {Sn14As16}, which is made up of a tetramer of alkyl-Sn-oxo subunits linked by four APA ligands and incorporated with a zigzag belt-like {Na6} cluster. This complex shows high water stability and finds potential application as an electrode decoration material in CO2 reduction. [ABSTRACT FROM AUTHOR]
