Pyrimidin-2-amine–1-phenylcyclopentane-1-carboxylic acid (1/1)

چکیده
In the crystal structure of the title co-crystal, C(4)H(5)N(3)·C(12)H(14)O(2), the components are linked by N-H⋯O and O-H⋯N hydrogen bonds. Self-assembly of these dimeric units results in a four-component supra-molecular unit featuring a homosynthon between two mol-ecules of the pyrimidin-2-amine involving two N-H⋯O hydrogen bonds, and two heterosynthons between each one mol-ecule of pyrimidin-2-amine and 1-phenyl-cyclo-pentane-1-carb-oxy-lic acid involving N-H⋯O and O-H⋯N hydrogen bonds.

In the title 1:1 adduct, C(7)H(6)N(2)S·C(9)H(10)O(5), all non-H atoms of the benzothia-zol-2-amine mol-ecule are essentially coplanar, with a maximum deviation of 0.0286 (9) Å for the S atom. In the crystal, inter-molecular N-H⋯O and O-H⋯N hydrogen bonds connect two mol-ecules of each type into centrosymmetric four-component clusters.

The asymmetric unit of the title compound, 2C5H6ClN3O·C4H6O4, consists of one 4-chloro-6-meth-oxy-pyrimidin-2-amine mol-ecule and one half-mol-ecule of succinic acid which lies about an inversion centre. In the crystal, the acid and base mol-ecules are linked through N-H⋯O and O-H⋯N hydrogen bonds, forming a tape along [1-10] in which R2(2)(8) and R4(2)(8) hydrogen-bond motifs are observed. The...

In the title co-crystal C(6)H(9)N(3)O(2)·C(10)H(9)NO(2), the 4,6-dimeth-oxy-pyrimidin-2-amine mol-ecule inter-acts with the carboxyl group of the 2-(1H-indol-3-yl)acetic acid mol-ecule through N-H⋯O and O-H⋯N hydrogen bonds, forming a cyclic hydrogen-bonded R(2) (2)(8) motif, which is further linked by an N-H⋯N hydrogen bond, forming a supra-molecular chain along the c axis. Neighboring chains ...

The title compound, C(13)H(17)N(5)OS, was obtained by cyclo-addition of 2-[2-(methyl-sulfan-yl)pyrimidin-4-yl]-3-oxo-propane-nitrile with (tetra-hydro-furan-3-yl)hydrazine dihydro-chloride and subsequent N-methyl-ation of 4-[2-(methyl-sulfan-yl)-pyrimidin-4-yl]-1-(tetra-hydro-furan-2-yl)-1H-pyrazol-5-amine with methyl iodide. The two mol-ecules in the asymmetric unit have opposite absolute conf...
