The structural characterization of a new quasi- undecahydrate of samarium(III) picrate is described. [ Sm ( pic )2(OH2)6]( pic ).43/4H2O is monoclinic, C 2/c, a 39.96(1), b 7.951(2), c 24.233(9) Ǻ, β 110.92(2)°, Z = 8, temperature c.295 K; R was 0.047 for 5010 'observed' diffractometer reflections. Like the cations of Part I, the present has two picrate and six aqua ligands; although the general stereochemistry is similar, the picrate ligands are both clearly unidentate, unlike previous arrays wherein one behaves in a quasi- bidentate mode utilizing an ortho-nitro oxygen atom.

The silatrane hydride compound, [N(CH2CH2O)3]SiH, reacts with CO2 in the presence of the [tris(2-pyridylthio)methyl]zinc hydride complex, [Tptm]ZnH, to afford the silyl formate and methoxide derivatives, [N(CH2CH2O)3]SiO2CH and [N(CH2CH2O)3]SiOCH3. The molecular structure of [N(CH2CH2O)3]SiO2CH has been determined by X-ray diffraction, thereby demonstrating that the formate ligand adopts a distal conformation in which the uncoordinated oxygen atom resides with a trans-like disposition relative to silicon. Density functional theory calculations indicate that the atrane motif of [N(CH2CH2O)3]SiO2CH is flexible, such that the energy of the molecule changes relatively little as the Si···N distance varies over the range 2.0–3.0 Å.

As part of our synthetic efforts for new triplesalen derivatives, we reacted 2,4,6-triacetyl- 1,3,5-trihydroxybenzene (1) with excess Cu(ClO4)2 · 6H2O, imidazole, and ethylenediamine. However, not the triple ketimine derivative was formed but the mononuclear CuII complex [LCuII(ImH)]ClO4 · 0.5EtOH · 0.5H2O (HL = 6-(1-(2-aminoethylimino)ethyl)-2,4-diacetyl-1,3,5-trihydroxybenzene) with only one ketimine function. This complex forms a one-dimensional coordination polymer in the solid state through the apical binding of a keto-oxygen atom of one cation to the CuII ion of a neighboring cation. Magnetic measurements reveal the presence of weak antiferromagnetic intra-chain interactions
