Kw. Henderson et al., SYNTHESIS OF HETEROLEPTIC BIS(AMIDES) - CRYSTAL-STRUCTURE OF THE REPRESENTATIVE COMPOUND, [(MG[N(PH)2][N(PH)(2-PYR)])2], Polyhedron, 12(20), 1993, pp. 2535-2538
Reaction of Ph(2-Pyr)NH with ''Mg(Bu)2'', followed by addition of amin
e substrates, gives heteroleptic magnesium bis(amides), one of which,
[{Mg[N(Ph)2][N(Ph)(2-Pyr)]}2], has been crystallographically character
ized and shown to be a dimer with a central, rectangular azamagnesacyc
lic ring.
