In the title compound, [Fe(C(5)H(5))(C(15)H(16)NO)], the two cyclo-penta-dienyl (Cp) rings are nearly parallel to each other, forming a dihedral angle of 3.7 (1)°, and adopt a staggered conformation. The amide group is almost perpendicular to the plane of the substituted Cp ring, with a C-N-C-C torsion angle of 101.3 (2)°, and the N and O atoms in the ethanoyl group are coplanar, with a C-N-C-O...

We exhibit seven linear codes exceeding the current best known minimum distance d for their dimension k and block length n. Each code is defined over F8, and their invariants [n, k, d] are given by [49, 13, 27], [49, 14, 26], [49, 16, 24], [49, 17, 23], [49, 19, 21], [49, 25, 16] and [49, 26, 15]. Our method includes an exhaustive search of all monomial evaluation codes generated by points in t...

In the crystal structure of the title compound, [Fe(C(5)H(5))(C(21)H(22)OP)], the cyclo-penta-dienyl (Cp) rings are almost parallel and are essentially eclipsed. The absolute configuration was determined as S for the planar and R for the central chirality.

The crystal structure of [3]ferrocenophan-1-one, [Fe(C(13)H(12)O)], has been redetermined at 150 K. The tethered cyclo-penta-dienyl (Cp) rings are tilted by 9.39 (18)° and assume an eclipsed conformation. The 1-oxopropane-1,3-diyl bridge has a pseudo-envelope conformation with the C=O group deviating by as much as 22.5 (2)° from coplanarity with its attached Cp ring.

The hydrophobically assisted switching phase (HASP) method was applied in the assembly of oligomannosides. A new mannosyl donor with high reactivity was selected after a series of optimization studies, which was suitable for the synthesis of oligomannosides via the HASP method. The practicability of the HASP method towards the synthesis of branched oligosaccharides was explored and two branched...
