6,7-Diphenyl-5-thia-7-azaspiro[2.6]nonan-8-one
The asymmetric unit of the title compound, C19H19NOS, contains two independent mol-ecules (A and B), in both of which the 1,3-thia-zepan-4-one ring adopts a chair-type conformation. The dihedral angles between the two phenyl rings are 65.28 (8) and 60.31 (9)° for mol-ecules A and B, respectively. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, resulting in a three-dimensional...

In the title compound, C(15)H(14)N(2)O(5)S(2)·CH(4)O, the six-membered ring fused to the β-lactam unit adopts a twisted conformation. In the crystal structure, the component mol-ecules are linked into a three-dimensional framework through inter-molecular N-H⋯S, N-H⋯O and O-H⋯O hydrogen bonds and C-H⋯O contacts.

In the title compound, C(14)H(14)N(2)O(5)S(2)·H(2)O, the six-membered ring fused to the β-lactam unit has a twisted conformation. Weak intra-molecular N-H⋯S and C-H⋯O inter-actions occur. Inter-molecular C-H⋯S, N-H⋯O, C-H⋯O and O-H⋯O hydrogen-bonding inter-actions stabilize the crystal structure, forming a three-dimensional network. Weak C-H⋯π inter-actions are also present.
متن کاملCholest-5-en-7-one
In the deca-hydro-phenanthrenone ring system of the title compound, C(27)H(44)O, the two cyclo-hexane rings adopt chair conformations, whereas the cyclo-hexene ring adopts an envelope conformation. The cyclo-pentane ring is twisted. In the crystal structure, mol-ecules are stacked along the a axis, but no significant inter-molecular inter-actions are observed.
