ABSTRACT: In the title compound, C(24)H(26)FN(3)O(4), the two aromatic rings form a dihedral angle of 88.81?(15)°. The cyclo-hexane ring adopts a chair conformation and the five-membered ring is essentially planar, with a maximum deviation from planarity of 0.041?(2)?Å. The crystal structure displays inter-molecular C-H?O and N-H?O hydrogen bonds.

In the crystal structure, mol-ecules are linked via weak inter-molecular C-H?O hydrogen bonds, forming extended chains along the b axis. Further stabilization is provided by weak C-H?? inter-actions.

4-(Pyrimidin-2-yl)-1-thia-4-aza-spiro-[4.5]decan-3-one.

Project description:The title compound, C(12)H(15)N(3)OS, features an envelope conformation for the 1,3-thia-zolidin-4-one ring with the S atom as the flap atom. The pyrimidine ring is almost orthogonal to the 1,3-thia-zolidin-4-one ring as indicated by the N-C-C-N torsion angle of -111.96?(18)°. Supra-molecular dimers are formed in the crystal structure through the agency of C-H?O contacts occurring between centrosymmetrically related mol-ecules. These are linked into supra-molecular tapes along [100] via C-H?S contacts.
