S-I-3. Stereotaxic Thalamolaminotomy

[μ-3-(Methyl­sulfan­yl)benzene-1,2-di­thiol­ato-1:2κ4 S,S′:S,S′]bis­[tri­carbonyl­iron(I)]

The title compound, [Fe2(C7H6S3)(CO)6], was prepared as a biomimic for the active site of [FeFe]-hydrogenases. The central Fe2S2 core is in a butterfly conformation and each Fe(I) atom has a pseudo-square-pyramidal coordination by three O atoms and two S atoms. The Fe-Fe distance is 2.471 (2) Å and the dihedral angle between the two Fe-S-Fe planes is 78.96 (7)°. The least-squares plane through ...

I-3: Hypogonadotropic Hypogonadism

Hypogonadotropic hypogonadism (HH) is an uncommon cause of male infertility and a congenital or secondary disorder characterized by delayed or absent sexual maturation. Congenital abnormalities leading to HH are usually the consequence of deficient GnRH secretion occurring either in isolation (idiopathic hypogonadotropic hypogonadism (IHH)), or in association with anosmia (Kallmann syndrome; KS...

un 1 99 8 S 3 × S 3 acts freely on S 3 × S 3

A free action of the direct product of two copies of the symmetric group on 3 elements on the cartesian product of two copies of the 3-sphere is constructed. This nonlinear action is constructed using surgery. The action provides a counterexample to a conjecture of Lewis made in 1968. Results of P. A. Smith [10] and J. Milnor [5] show that a dihedral group cannot act freely on a sphere. This im...
