title: 2-Amino-4,6-bis(benzyloxy)-5-nitrosopyrimidine: chains built from three-centre N[bond]H...(N,O) and N[bond]H...pi(arene) hydrogen bonds.
abstract: The molecules of the title compound, C(18)H(16)N(4)O(3), exhibit a very polarized molecular-electronic structure. The molecules are linked into chains by a combination of an asymmetric three-centre N[bond]H...(N,O) hydrogen bond [H...N 2.19, H...O 2.54, N...N 3.041 (4) and N...O 2.977 (4) A, and N[bond]H...N 168, N[bond]H...O 112 and N...H...O 67 degrees ] and an N[bond]H...pi(arene) interaction [H...Cg 2.67 A, N...Cg 3.496 (4) A and N[bond]H...Cg 163 degrees; Cg is a benzyl ring centroid].
