The 3 centre-4 electrons (3c-4e) and the donor/acceptor or charge-transfer models for the description of the chemical bond in linear three-body systems, such as I3 − and related electron-rich (22 shell electrons) systems, are comparatively discussed on the grounds of structural data from a search of the Cambridge Structural Database (CSD). Both models account for a total bond order of 1 in these systems, and while the former fits better symmetric systems, the latter describes better strongly asymmetric situations. The 3c-4e MO scheme shows that any linear system formed by three aligned closed-shell species (24 shell electrons overall) has reason to exist provided that two electrons are removed from it to afford a 22 shell electrons three-body system: all combinations of three closed-shell halides and/or chalcogenides are considered here. A survey of the literature shows that most of these three-body systems exist. With some exceptions, their structural features vary continuously from the symmetric situation showing two equal bonds to very asymmetric situations in which one bond approaches to the value corresponding to a single bond and the second one to the sum of the van der Waals radii of the involved atoms. This indicates that the potential energy surface of these three-body systems is fairly flat, and that the chemical surrounding of the chalcogen/halogen atoms can play an important role in freezing different structural situations; this is well documented for the I3 − anion. The existence of correlations between the two bond distances and more importantly the linearity observed for all these systems, independently on the degree of their asymmetry, support the state of hypervalency of the central atom.

Chloro-Cycloselenazenium Hexachloroantimonate(V), Synthesis, Crystal Structure[Se3N2Cl]+SbCl6~ has been prepared as red crystals by the reaction of the nitride chloride Se2NCl5 with antimony(III) chloride in dichloro methane. It was characterized by a crystal struc ture determination. Space group PI, Z = 2, 4396 observed unique reflections, R = 0.030. Lattice di mensions at -80 °C: a = 698.2, b = 699.7, c = 1510.5 pm, a = 89.45°, ß = 86.18°, y = 68.22°. The struc ture consists of two symmetry-independent ca tions and two symmetry independent anions, which differ only slightly from each other. The cations contain Se3N2 five-membered rings, which deviate very little from planarity as shown by fol ding angles of 14° and 18°. The Se-N bond distan ces are between 171.4 and 176.4 pm suggesting double-bond constituents.

Novel Cationic Selenium-Cluster Nitride Species [SenN]+ (n=1-11) Formed by Laser Ablation of a Se Target in the Presence of N2

et al. 2001

Nitride cations of selenium clusters [SenN]+ (n = 1-11) were readily produced by laser ablation of a selenium disk that was surrounded by a trace amount of nitrogen seeded in helium and followed by supersonic expansion into a high vacuum. Even at high nitrogen partial pressures, the cluster mononitride cations were found to be essentially the only nitride products in the whole size range we studied. The exception was [Se3N2]+, which is known to be a stable five-membered ring with seven pi electrons. We propose that, in the laser-ablation plasma, the selenium clusters with n > 2 take on a chain conformation, and that the N species links the two ends of the selenium chains, thus forming stable mononitride cations of the cyclic selenium clusters. Their stability is supported by the results of ab initio calculations (at both B3LYP/ 6-31 + G* and MP2/6-31 + G* levels) and of mass-selected cluster-ion photodissociation experiments.
