In the salt, C7H16N+×C16H28F3N3O2P-, the P atom shows tetrahedral coordination. Two ion pairs are linked by N-H×××O hydrogen bonds across a center of inversion. The phosphoryl and carbonyl groups are staggered [O-P-N-C = ...

A new amidophosphoester, (4-Cl-C6H4O)(OC4H8N)2PO, was synthesized and characterized by spectroscopic methods (IR, 31P-, 13C-, 1H-NMR) and single-crystal X-ray diffraction. The crystal belongs to the space group P21/c, and ...
