- Аннотация: The series of organotin halide complexes with tetraethyl ethylene- and propylene-diphosphonates R(n)SnX(4-n) . L [n=0, X=Cl; n=1, R=Me, X=Cl, Br; n=1, R=Ph, X=Cl; n=2, R=Me, Et, Bu, X=Cl, Br; n=2, R=Ph, X=Cl; L=(EtO)(2)P(O)CH(2)CHR'P(O)(OEt)(2), R'=H, Me] were synthesized and characterized by means of NMR and Mossbauer spectroscopy. The crystal structure of the complex of diphenyltin dichloride with propylenediphosphonate was determined. The complex consists of polymer chains with bridging bidentate ligands and an octahedral tin environment containing two types of phosphoryl fragments. All of the R(2)SnX(2) adducts have trans-R(2)SnX(4) geometries of tin coordination octahedra according to the quadrupole splitting values in the Mossbauer spectra. The P-31 and Sn-119 NMR studies at low temperatures revealed that RSnHal(3), complexes in solution form isomers with different mutual orientations of phosphoryl ligands and organic groups in the coordination sphere. The diethyltin dichloride adduct with ethylene-diphosphonate appeared to be active against lung cancer NCI-H522 cells.
