title: 4-Amino-2-phenoxy-pyrimidine.
abstract: In the title compound, C(10)H(9)N(3)O, the organic rings linked to the ether O atom make a dihedral angle of 76.8 (1)° and the C-O-C angle is widened to 119.07 (15)°. In the crystal, adjacent mol-ecules are connected by an N-H⋯N hydrogen bond, generating a chain running parallel to the b axis. The crystal is a non-merohedral twin with a ratio of twin components of 0.508 (3):0.492 (3).
