Abstract

Reactions of K₁₂Si₁₇ with the low-valent transition-metal complex Mo(CO)₃(C₇H₈) in ethylenediamine/toluene solutions in the presence of 2,2,2-cryptand yield the {Si(NHCH₂CH₂NH)₃[Mo(CO)₃]₂}^2- dianion, which contains an octahedral Si(NHCH₂CH₂NH)₃^2- subunit. The SiN₆ core comprises a rare example of a doubly deprotonated ethylenediame ligand in a coordination complex and is also the first structurally characterized example of a homoleptic Si(N∩N)₃ trischelate. Its structure and spectroscopic properties are described.
