Abstract: In the title compound, C16H22N3OP·H2O, the P atom adopts a distorted tetrahedral environment with the bond angles around the P atom in the range 99.98 (7)-116.20 (7)°. The P-N bond length in the [(CH3)2N]P(O) fragment [1.6392 (14) Å] is slightly shorter than two other P-N bonds [1.6439 (15) and 1.6530 (14) Å]. In the (CH3)2NP(O) fragment, one of the methyl groups is syn to the P=O bond, whereas the other one is anti to the P=O bond [C-N-P=O torsion angles = 4.80 (17) and -174.57 (15)°]. In the crystal, the water molecules form hydrogen bonds to the O atoms of the P=O bond of two different molecules and act as acceptors for the two amino H atoms of the same molecule. As a result, chains parallel to  are formed.
