چکیده
The title compound, C(20)H(32)N(2)O(2)S, the condensation product of a thio-acetohydrazine and acetone, has a two-coordinate S atom and the angle at this atom is 100.7 (1)°. The (CH(3))C=N-NH-C(O)- substituent engages in N-H⋯O hydrogen-bonding inter-actions with the substituent of an adjacent mol-ecule across a center of inversion, generating a dimeric structure.

In the title compound, C(30)H(36)N(2)O(2)S, the dihedral angle between the two aromatic rings of the biphenyl residue is 31.2 (1)°. The two methyl-ene C atoms subtend an angle of 99.9 (1)° at the S atom. In the crystal, mol-ecules form inversion dimers linked by pairs of N-H⋯O hydrogen bonds. The hydroxyl group is shielded by the tert-butyl residues and is therefore not involved in any hydrogen...

The title compound, [Sn(C(6)H(5))(3)(C(17)H(25)O(3)S)](n), comprises two symmetry-independent five-coordinated triphenyl-tin mol-ecules which are linked by carboxyl-ate bridges into a polymeric chain. The Sn(IV) atom is in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry. The presence of two bulky tert-butyl groups on the benzene ring prevents any hydrogen-bonding inter-actions involv...
