Abstract

A bimetallic oxalamidino complex of neodymium [(Cp″)2Nd(NR)2C—C(NR′)2Nd(Cp″)2][Cp″=η 5-C5H3-1,3-(SiMe3)2, R=C6H11](2) was obtained via reaction between NdI2 and carbodiimide[RN=C=NR] (R=C6H11)(molar ratio 1:1) in tetrahydrofuran(THF) solution, followed by the addition of [KCp″(THF)](1)(molar ratio 1:2) at a low temperature through a reductive-coupling reaction with carbodiimide. The structure of the intermediate product was confirmed by means of elemental analysis, 1H NMR and 13C NMR. Characterization of the product by single crystal X-ray diffraction confirmed the diamidinate type of structure.
