A number of penta- and hexacoordinated organotin(IV) complexes and tetracoordinated tin(II) complexes of compositions Me2SnCl[RCOC:CON(C6H5)N:CCH3] (where R = - CH(3), -p-ClC(6)H(4), and -C(6)H(5)), Me2Sn[RCOC:CON(C6H5)N:CCH3]2 (where R = -CH(3), and -C(6)H(5)), and Sn(II) [RCOC:CON(C6H5)N:CCH3]2 (where R = -p-ClC(6)H(4) and -C(6)H(5)) were screened for their toxicity against Musca domestica (house fly). In general, organotin(IV) complexes contribute more to the activity than tin(II) complexes.

The pentafluorophenyl moiety CF was succesfully employed for the first time in lead(II) chemistry. We are reporting on the stable and soluble organolead(II) polymer [Pb(CF)(dx)] (dx = dioxane). An example of a Pb(II) "ate" complex paired with a trimetallic magnesium cation is also presented.

We report the syntheses of tin(II) salts of the types [LSnX]SnX [L=2,6-{(i-PrO)(O)P}CHN: 1, X=Cl; 2, X=Br], [LSnCl]SnCl [L=2-{(i-PrO)Ph(O)P}-6-{(i-PrO)(O)P}CHN: 3], [LSnX]SnX [L=2,6-{MeO(O)C}CHN: 4, X=Cl; 5, X=Br], [LSnX]SnX [L=2,6-{EtN(O)C}CHN: 6, X=Cl; 7, X=Br]. These compounds were obtained by addition of SnX to the corresponding ligand inducing autoionization of the respective tin(II) halide. The thermal stability of 1, 3, and 4 was elucidated, giving, under ester cleavage and cyclisation, the tin(II) derivatives 8-12.

A series of iso-carbamate complexes have been synthesized by the reaction of [Sn(OPr)] or [Sn(OBu)] with either aryl or alkyl isocyanates, ONC-R (R = 2,4,6-trimethylphenyl (Mes), 2,6-diisopropylphenyl (Dipp), isopropyl (Pr), cyclohexyl (Cy) and -butyl (Bu)). In the case of aryl isocyanates, mono-insertion occurs to form structurally characterized complexes [Sn{κ--R-NC(OPr)O}(μ-OPr)] (: R = Mes, : R = Dipp) and [Sn{κ--R-NC(OBu)O}(μ-OBu)] (: R = Mes, : R = Dipp). The complicated solution-state chemistry of these species has been explored using H DOSY experiments.

Meso-octaalkylcalix[4]pyrrolates are a class of redox-active porphyrinogen ligands. They have been well established in d- and f-block chemistry for over three decades but have only recently been introduced as ligands for p-block elements. Here, we present a study on the influence of meso-substituents on the redox chemistry of calix[4]pyrrolato stannate(II) dianions [2] (R=Me, Et).
