title: Synthesis and biological studies on some organo-tin and lead halo and mixed halo-pseudohalo anionic complexes.
abstract: Some new anionic complexes of organo-tin(IV) and lead (IV) isolated in combination of tetraorgano-ammonium phosphonium and stibonium cation(s). L[R4-nMXnY] and L2[R2MX2Y2], where R = C2H5, C4H9 or C6H5; M = Sn or Pb; X = Y = Cl = Br, I, N3, NCS; n = 1, 2 and L = R4M1 (M1 = N, P, Sb), whose structures were confirmed by correct elemental analyses, molar conductance values, van't Hoff factor and IR spectral studies, were synthesized and evaluated for anti-convulsant activity in vivo and antiviral and antibacterial activity in vitro. A few of them exhibited promising activity. In addition, the toxicity (ALD50) and effects on the central nervous system of these complexes have been studied in mice.
