Abstract
Complexes [[graphic omitted]Me2)3][Ln = Y (1) or Nd (2)] are crystalline and hydrocarbon-soluble; they are the first examples of monomeric, homoleptic Group 3 or lanthanoid metal alkoxides and also the first crystallographically authenticated Group 3 or early (f0–f3) lanthanoid metal tertiary phosphine complexes [1J(31P–89Y)= 59 Hz], with the following geometric parameters for (1)[or (2) in square brackets]: 2.090(4)[2.174(2)], 3.045(2)[3.154(2)]Å, and 110.5(2)[114.5(1)]°.Keywords
