In the title compound, C(13)H(16)N(2)O, the cyclo-hexane ring adopts a chair conformation. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains propagating in .
In the title compound, [Sn(C(6)H(5))(2)(C(11)H(11)NO(4))], the tin(IV) atom is penta-coordinated in a distorted trigonal-bipyramidal SnC(2)NO(2) geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. Weak C-H⋯O inter-actions further link the dimers into chains extending in .
In the title compound, C(18)H(14)N(2)O(2)·H(2)O, the dihedral angle between the benzene ring and the naphthalene system is 5.18 (10)°. Intra-molecular N-H⋯O hydrogen bonds influence the molecular conformation. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds are observed as well as π-π inter-actions between the phenyl ring and the substituted… (More)
