title: Diisopropyl {[(R)-2-(2-amino-6-chloro-9H-purin-9-yl)-1-methyl-eth-oxy]meth-yl}-phospho-nate.
abstract: In the title compound, C(15)H(25)ClN(5)O(4)P, the r.m.s. deviation for the purine ring system is 0.0165 Å. The coordination about the P atom is a distorted tetrahedron [O=P-O angles = 116.70 (6) and 109.87 (6)°]. In the crystal, molecules are linked by N-H⋯O hydrogen bonds, generating a three-dimensional network.
