A new method of syntheses of 18-membered macrocyclic diphenyltin(IV) compounds and crystal structures of {Ph2Sn[S(C6H3NO)O]}3·Y (Y = 2H2O or 4C6H6) and {Ph3Sn[S(C6H3NO)O]SnPh3(EtOH)}·[EtOH]

Two diphenyltin(IV) compounds: {Ph2Sn[S(C6H3NO)O]}3·Y (Y = 2H2O, 1; 4C6H6, 2) have been unexpectedly obtained by the reactions of triphenyltin chloride with 2-mercaptonicotinic acid in the presence of Et3N. However, by the reaction of the same reactants in the presence of EtONa, only a new triphenyltin(IV) compound ({Ph3Sn[S(C6H3NO)O]SnPh3(EtOH)}·[EtOH], 3) was obtained. The X-ray analyses reveal that compounds 1 and 2 are trinuclear, 18-membered macrocyclic compounds while 3 is a dinuclear compound. Specially, π-π stacking interaction was recognized in crystals of compound 1, which makes it a dimer. Co-crystallization was found in the crystals of all the three compounds 1, 2, and 3, the co-crystallized solvent molecules are water, benzene, and ethanol molecules, respectively. A possible dephenylation mechanism of 1 and 2 was illustrated in detail.Key words: triphenyltin, 2-mercaptonicotinic acid, dephenylation, macrocyclic, π-π stacking interaction, co-crystallization, crystal structure.

Title Molecule

In the title molecule, C13H13N3O2, the planes of the benzene and imidazole rings form a dihedral angle of 7.72 (5)°. In the crystal, molecules are linked by weak C—H...N and C—H...O hydrogen bonds, forming layers parallel to (100). A weak C—H...π interaction connects these layers into a three-dimensional network. A π–π stacking interaction, with a centroid–centroid distance of 3.5373 (9) Å, is also observed.

In the title compound, C25H14F3N3O3, the dihedral angle between the planes of the benz[4,5]imidazo[1,2-a]pyrimidine unit (r.m.s. deviation = 0.035 Å) and the benzochromene ring system (r.m.s. deviation = 0.106 Å) is 72.82 (5)°. In the crystal, molecules are linked by C—H...O interactions, generating [010]C(9) chains. A weak aromatic π–π stacking interaction [centroid–centroid separation = 3.5376 (15) Å] is also observed.

In the title compound, C9H10N2O4, the planes of the nitro groups subtend dihedral angles of 55.04 (15) and 63.23 (15)° with that of the aromatic ring. These tilts are in opposite senses and the molecule possesses approximate mirror symmetry about a plane normal to the molecule. In the crystal, molecules form stacks in the [100] direction with adjacent molecules related by translation, although the centroid–centroid separation of 4.136 (5) Å is probably too long to regard as a significant aromatic π–π stacking interaction. An extremely weak C—H...O interaction is also present.
