A novel example of self-assembly in lanthanide chemistry: synthesis and molecular structure of [Na(EtOH)6][Y9(µ4-O)2(µ3-OH)8{µ-η2-MeC(O)CHC(O)OEt}8{η2-MeC(O)CHC(O)OEt}8]†
Abstract
The reaction between yttrium nitrate pentahydrate and the sodium salt of allyl acetatoacetate afforded nonanuclear cluster anions [Y9(µ4-O)2(µ3-OH)8{MeC(O)CHC(O)Z}16]–, the functional group Z being the initial allyl one OCH2CHCH2 or an ethoxide depending on the experimental conditions.
