RESUMO
Two independent diphenyl-tin mol-ecules and two independent methanol mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(6)H(5))(2)(C(17)H(14)N(2)O(3))]·CH(3)OH. The Sn atom in each is five-coordinated by a tridentate ligand and the ipso-C atoms of the Sn-bound benzene substituents. The resulting C(2)N(2)O donor set defines a coordination geometry that is inter-mediate between trigonal-bipyramidal (TP) and square-pyramidal (SP), with one mol-ecule slightly tending towards TP and the other slightly towards SP. The mol-ecules differ in terms of the relative orientations of the terminal benzene rings [dihedral angles = 45.71â (18) and 53.98â (17)°] and of the Sn-bound benzene substituents [dihedral angles = 59.5â (2) and 45.77â (18)°, respectively]. The most prominent feature of the crystal packing is the formation of four-mol-ecule aggregates via O-Hâ¯O and O-Hâ¯N hydrogen bonds, in which the hy-droxy group is connected to a methanol mol-ecule which, in turn, is linked to a non-coordinating N atom. Weak C-Hâ¯π inter-actions also occur.
RESUMO
The Sn(IV) atom in the title compound, [Sn(CH(3))(2)(C(17)H(14)N(2)O(3))], is five-coordinated within a C(2)N(2)O donor set provided by the N,N,O-tridentate ligand and two methyl groups. The resultant coordination geometry is inter-mediate between trigonal-bipyramidal and square-pyramidal. In the crystal, supra-molecular zigzag chains propagating along the c- axis direction are mediated by O-Hâ¯O hydrogen bonds, and weak C-Hâ¯π inter-actions consolidate the packing.
RESUMO
Two independent but very similar mol-ecules comprise the asymmetric unit of the title compound, [Sn(CH(3))(2)(C(18)H(12)N(2)O(3))]. Each Sn atom is coordinated by two methyl groups and two O atoms and an N atom from the dinegative tridentate ligand. The resultant C(2)NO(2) donor set defines a coordination geometry inter-mediate between square-pyramidal and trigonal-pyramidal, with a small tendency towards the former. Zigzag chains running along the a axis mediated by O-Hâ¯N hydrogen bonding characterize the crystal packing. These are connected into layers in the ab plane by a combination of C-Hâ¯N and π-π [centroid-centroid distances = 3.658â (2) and 3.6740â (18)â Å] inter-actions. The layers are connected along the c axis via C-Hâ¯O inter-actions.
