TL;DR: Iodination reactions of various phosphiniminocyclotrithiazenes [R3PNS3N3; R = (i) phenyl-, (ii) morpholino-, and (iii) p-chlorophenyl-] have been studied under different experimental conditions.
Abstract: Iodination reactions of various phosphiniminocyclotrithiazenes [R3PNS3N3; R = (i) phenyl-, (ii) morpholino-, and (iii) p-chlorophenyl-] have been studied under different experimental conditions. Iodination of Ph3PNS3N3 yields interesting products such as [(Ph3PN)2S3N3]I3, ((Ph3PN)3S)2I4, (Ph3PNH2)I3, ((Ph3PSI2)2I2, and [(Ph3PN)3SO]2I6 depending on the experimental conditions. All the products have been isolated and characterized by the spectroscopic and analytical techniques.

TL;DR: Some phosphazenium chloride salts of the type [R3PNH2]-Cl−, where R = phenyl, p-chlorophenyl and morpholino, were synthesized by the reaction of the corresponding phosphiniminocyclotrithiazene compounds with diphenyldichlorosilane in acetonitrile.
Abstract: Some phosphazenium chloride salts of the type [R3PNH2]+Cl−, where R = phenyl, p-chlorophenyl and morpholino, were synthesized by the reaction of the corresponding phosphiniminocyclotrithiazene compounds (R3PNS3N3) with diphenyldichlorosilane in acetonitrile. All the products were characterized by analytical and spectroscopic data. The single crystal X-ray structure of [Ph3PNH2]+Cl− was reinvestigated with one mole of water molecule in the crystal lattice, showing an intermolecular hydrogen bonding.

TL;DR: The usefulness of the Mayer bond order has been tested in a number of inorganic molecules including sulfur-nitrogen rings, halogen-oxide molecules and transition metal dichloride molecules as discussed by the authors.
Abstract: The bonding in molecules is most often described using the classical chemical ideas of covalency (bond multiplicity) and ionicity (atomic charges). The Mayer bond order is a natural extension of the Wiberg bond order, which has proved extremely useful in bonding analysis using semi-empirical computational methods, and the Mulliken population analysis to ab initio theories. The usefulness of the Mayer bond order has been tested in a number of inorganic molecules including sulfur–nitrogen rings, halogen–oxide molecules and transition metal dichloride molecules. The basis set dependence of the Mayer bond order is tested through the case studies presented. It is shown that the bond order can be fully or partially decomposed into the contributions from symmetry types for many interactions of interest to the inorganic chemist. The power of this approach is shown by examining the bonding in a variety of systems and is illustrated by detailed studies of the role of the ring size and electron count on the bonding in S–N rings, the role of hypervalency in the relative stabilities of mixed hydrogen and halogen peroxide isomers and the importance of s–d hybridization in the 3d transition metal dichloride molecules.
