pyridylmethanol (R′OH) provided the dinuclear complexes LCu(μ-OR′)}2 (R = naphtyl, CHPh2, 2,6-xylyl, 2,6-diisopropylphenyl (diip), or p-bromobenzyl). All complexes crystallized as dinuclear compounds with a square-pyramidal coordination geometry around copper and either imine or pyridine (for R = diip) in the apical position. The naphthyl-substituted complex was inactive in rac-lactide polymerization
