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)32– 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.
