✦ Synopsis

Ph 3 Ge) 2 Eu(THF) 4 (1 a) and (Ph 3 Ge) 2 Eu(DME) 3 (1 b) have been synthesized by reacting Ph 3 GeH with europium naphthalene, C 10 H 8 Eu(THF) 2 , in THF or DME, respectively. The reaction of Ph 3 GeH with C 10 H 8 [EuI(DME) 2 ] 2 in DME yielded Ph 3 GeEuI(DME) 2 (2). The addition of two equivalents of CH 3 I to a solution of 1 b in THF produced Ph 3 GeMe and EuI 2 (DME) 2 with al-most quantitative yields. Complex 2 easily disproportionates forming mixtures of 1 b and EuI 2 (DME) 2 . The molecular structure of 1 b was determined from X-ray diffraction data.
