Evaluation of Sn(II) aminoalkoxide precursors for atomic layer deposition of SnO thin films.

We have successfully prepared and structurally characterized a family of eight tin(II) heteroleptic complexes, [Sn(NR)(ON)] (NR = NMe (1a-d) or N(SiMe) (2a-d); = 1 or 2) and four homoleptic systems, [Sn(κ-ON)] (3a-d) from a series of aminoalcohols and fluorinated aminoalcohols (H{ON}) having a different number of methyl/trifluoromethyl substituents at the α-carbon atom, [HOC(R)(R)CHNMe] (R = R = H (H{dmae}) (a); R = H, R = Me (H{dmap}) (b); R = R = Me (H{dmamp}) (c); R = R = CF (H{Fdmamp}) (d)). The synthetic route used reactions of either [Sn{N(SiMe)}] or [Sn(NMe)] with one or two equivalents of the aminoalcohols (a-d) in dry aprotic solvents leading to elimination of amines and formation of the Sn(II) species 1a-d, 2a-d and 3a-d respectively. All complexes were thoroughly characterized by NMR spectroscopy (H, C, F, and Sn) as well as single-crystal X-ray diffraction studies.

Meiotic Cohesin and Variants Associated With Human Reproductive Aging and Disease.

Successful human reproduction relies on the well-orchestrated development of competent gametes through the process of meiosis. The loading of cohesin, a multi-protein complex, is a key event in the initiation of mammalian meiosis. Establishment of sister chromatid cohesion via cohesin rings is essential for ensuring homologous recombination-mediated DNA repair and future proper chromosome segregation.

Synthesis, characterisation and thermal properties of Sn(ii) pyrrolide complexes.

SnO is a rare example of a stable p-type semiconductor material. Here, we describe the synthesis and characterisation of a family of Sn(ii) pyrrolide complexes for future application in the MOCVD and ALD of tin containing thin films. Reaction of the Sn(ii) amide complex, [{(Me3Si)2N}2Sn], with the N,N-bidentate pyrrole pro-ligand, L1H, forms the hetero- and homoleptic complexes [{L1}Sn{N(SiMe3)2}] (1) and [{L1}2Sn] (2), respectively, bearing the 2-dimethylaminomethyl-pyrrolide ligand (L1).
