Monomeric and Dimeric Sodium Amides

Very little information is available for monomeric sodium amides. Addition of pmdeta to NaN(CH2Ph)(CHMePh) effects its transformation into the monomeric l,3-diphenyl-2-azallyl salts [(pmdeta)NaN(CHPh)2] and (pmdeta) a (CHPh)(C lePh)J. However, the sodium hydrazide salt [(thf)3NaN(Ph)N(SiMe3)2] crystallizes as monomers featuring 

The formation of discrete frameworks is also possible via the chelation of multidentate multidentate ligands.An example of this coordination mode is observed in the enamide [Na N(H)(=CH2)CPh (pmdeta)]2, which has a planar (NaNNaN) core containing five-coordinate sodium ions with average distances of 2.41 and 2.55 A iorendo- and cxo-cyclic [Na(NPrty)-
