    Notes: The title compound, C16H12N4O, was obtained through a two-step process. There are two molecules in the asymmetric unit with essentially equal bond lengths. The phenyl and oxazole rings are essentially coplanar. Steric interactions between the two halves of the molecule produce a wide angle at the central C atom.

    Notes: The title compound, C14H12FNO3S, was used as an activating agent for a chemical synthesis, from which it recrystallized immediately. In the structure, one intramolecular hydrogen bond was found, which leads to the formation of a six-membered ring within one half of the molecule. In the other half of the molecule, there is a disubstituted benzene ring. The electron-withdrawing effect of the S atom and the electron-releasing effect of the opposite methyl substituent are both observed in this structure.

    Notes: The title compound, cis-[W(CO)2(dppe)2] [dppe is 1,2-ethanediylbis(diphenylphosphine), C26H24P2], was obtained as a by-product during the preparation of the dinitrogen complex trans-[W(CO)(N2)(dppe)2]. The crystal structure of the benzene sesquisolvate, i.e. cis-[W(C26H24P2)2(CO)2]·1.5C6H6, has been determined.

    Notes: It was planned to sythesize morpholinedithiomonometaphosphoryl morpholinide by reaction of pyridinedithiomonometaphosphoryl chloride with 4-(trimethylsilyl)morpholine. But due to traces of water the title compound was formed as by-product, (I).

    Notes: By reaction of pyridine dithiomonometaphosphoryl fluoride with ethyldiphenylphosphine in the presence of traces of water, we isolated crystals of the title compound, (I). In the structure of this salt, two kinds of hydrogen bonds were detected. They link N—H (part of the cation), as well as one O—H group (part of the anion), to the phosphoryl O atom of the anion. The donor–acceptor distances are 2.654 (1) and 2.568 (1) Å, respectively. The P—O and P—S bond lengths are 1.514 (2) and 1.967 (1) Å, respectively, which fall therefore in the range of a 1.5-fold bond.

    Notes: In comparison with the known orthorhombic polymorph oftrans-2,4-di-tert-butyl-2,4-dithioxo-1,3-dithia-2,4-diphosphetane, C8H18P2S4, (I) [Shore, Pennington, Noble & Cordes (1988). Phosphorous Sulfur, 39, 153–157], the new crystallographic modification is monoclinic and the corresponding solid density is markedly higher. In both structures, the molecules have 2/m symmetry imposed by space-group symmetry and all corresponding bond lengths and angles are equal within the limits of errors.

    Notes: trans-[MoCl2(dppe)2] [dppe is 1,2-ethanediylbis(diphenylphosphine), C26H24P2] was obtained as a side product from the reaction of trans-[Mo(dppe)2(N2)2] with Cp*GeCl to give the germylyne complex trans-[Cl(dppe)2Mo[triple-bond]Ge(η1-Cp*)]. The crystal structures of the hemipentane (0.5C5H12) and ditetrahydrofuran (2C4H8O) solvates of trans-[MoCl2(dppe)2], (IIIa) and (IIIb), respectively, have been determined.

    Notes: Crystals of the title compound, C9H12O, were formed as an unexpected by-product during the recrystallization of (2R,3R)-α,α,α′,α′-tetramesityl-1,4-dioxaspiro[4,5]decane-2,3-dimethanol from hexane/ethyl acetate (7:3). Strong hydrogen bonds between hydroxide groups connect the molecules around one set of four symmetry-equivalent 21 axes.

    Notes: The title molecule, C16H22O2, reveals Ci point symmetry in the crystal structure. The structure was disordered. The pyran ring is not planar; the O atom lies significantly out of the least-squares plane (ten times the r.m.s. deviation of all six atoms).
