Crystal structure of 6-benzylamino-9-[2-tetrahydropyranyl]-9H-purine.
C17H19O2N5 is monoclinic, P2(1)/n. Unit-cell dimensions at 293 K are a = 10.802(1), b = 24.085(2), c = 12.933(1)A, beta = 106.119(6) degrees, V = 3232.4(6)A3, Dx = 1.271 g/cm3, and Z = 8. The R value is 0.068 for 3017 observed reflections. There are two independent molecules in the asymmetric unit, denoted by A and B. In A, the dihedral angle between the adenine moiety and the phenyl ring is 73...

The title compound, C(11)H(6)ClN(5)O(4)S, crystallized with two independent mol-ecules in the asymmetric unit. The benzene ring makes dihedral angles of 66.46 (8) and 85.77 (9)° with the mean plane of the purine ring in the two mol-ecules. In the crystal, inter-molecular π-π stacking inter-actions [centroid-centroid distance = 3.8968 (12) Å], C-Cl⋯π inter-actions [Cl⋯centroid = 3.2505 (10) Å, C...

In the title compound, C17H20ClN5O2, the benzene ring and the purine ring system make a dihedral angle of 78.56 (4)°. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers. C-H⋯O and C-H⋯Cl contacts further link the mol-ecules, forming a three-dimensional network.

The mol-ecule of the title compound, C19H23N5O3, contains six-membered pyrimidine and five-membered imidazole rings merged into the essentially planar purine skeleton (r.m.s. deviation = 0.01 Å). In the crystal, pairs of N-H⋯N hydrogen bonds link mol-ecules into inversion dimers. The dimers are linked via C-H⋯O hydrogen bonds, forming double-stranded chains propagating along [001]. These chains...
