Metal carbacylamidophosphates: ability of coordination patterns to di- and polymerization

Diorganotin(IV) complexes of N-mono-, di- and tri-chloroacetyl, N′,N″-bis(isopropyl) phosphoric triamide

“…Different di-and polymeric complexes of deprotonated tri chloroacetyl derivative have been synthesized either by h 2 -phosphorylic bridges, donor atoms of the substitute (R 0 ) or employing an additional bridging ligand [12,13].…”

Different orientations of C=O versus P=O in P(O)NHC(O) skeleton: the first study on an aliphatic diazaphosphorinane with a gauche orientation

“…The anti orientation is preferred for the C=O versus P=O unit [6,7]. Some researchers have employed the anionic form [P(O)NC(O)] -to obtain compounds with a non-anti orientation [8] and better donority properties [9]. Despite the numerous structures reported in this series [10][11][12][13][14][15][16][17][18][19], there are a few neutral structures with synclinal orientation [2,5,[13][14][15][16][17]19].…”

New organotin(IV) complexes of nicotinamide, isonicotinamide and some of their novel phosphoric triamide derivatives: Syntheses, spectroscopic study and crystal structures

“…Although numerous derivatives of nicotin-and isonicotinamide have been reported in the literature we could not find any phosphoramidate containing these amides. Phosphoramidates including -C(O)N(H)-P(O)-moiety have been used as O-donor ligands in the reaction with various metal ions up to now [4][5][6][7][8][9][10][11][12][13][14][15]. The presence of a peptide group in these compounds causes its diverse biological activity and used as anticancer drugs [16].…”
