Yttrium and erbium halide complexes with [{Ti(eta5-C5Me5)(mu-NH)}3(mu3-N)] as a neutral tridentate ligand

Treatment of {TiCp*(mu-NH)} 3(mu 3-N)] ( 1; Cp* = eta (5)-C 5Me 5) with yttrium and erbium halide complexes MCl 3(THF) 3.5] and MCpCl 2(THF) 3] (Cp = eta (5)-C 5H 5) gives cube-type adducts Cl 3M{(mu 3-NH) 3Ti 3Cp* 3(mu 3-N)}] and CpCl 2M{(mu 3-NH) 3Ti 3Cp* 3(mu 3-N)}]. An analogous reaction of 1 with {MCp 2Cl} 2] in toluene affords Cp 3M(mu-Cl)ClCpM{(mu 3-NH) 3Ti 3Cp* 3(mu 3-N)}] (M = Y, Er).
