Selenium nitride

The value reported in [82WAG/EVA] is 708 kJ-moT, and is obviously based on the early [1884BER/VIE] study.

In spite of the hazardous nature of Sc4N4, this binary selenium nitride has been used for the synthesis of other Se-N compounds, all of which have sulfur analogues (Scheme 5.2). " However, safer alternatives to the use of Sc4N4, e.g., selenium-nitrogen halides and silicon-nitrogen-selenium reagents, are available for the development of Se-N chemistry. ...

Kennett, F. A. et al., J. Chem. Soc., Dalton Trans., 1982, 851-857 In attempted preparation of poly(selenium nitride), the black solid formed by interaction with selenium tetrabromide in acetonitrile exploded violently within 1 min at 0°C. The solid produced from diselenium tetrachloride in acetonitrile exploded at around 100°C, and in dichloromethane the product exploded in contact with a nickel spatula.

Raman spectroscopy is a useful probe for detecting transannular S - S interactions in bicyclic or cage S-N molecules or ions. The strongly Raman active vibrations occur at frequencies in the range 180-300 cm-1, and for S- -S distances in the range 2.4-2.7 A. On the basis of symmetry considerations, the Raman spectrum of the mixed sulfur-selenium nitride S2Se2N4 was assigned to the 1,5- rather than the 1,3- isomer.37...

If the oxychloride is applied in dilute benzene solution some nitrogen selenide or selenium nitride is also formed.3 With liquid ammonia in the presence of ether in open vessels, the primary product is the compound SeOCl2.4NH3, which is decomposed by water into selenium, selenium nitride, ammonium chloride, ammonium selenite and selenious acid in a sealed tube, selenium nitride is formed in comparatively good yield.4...

After investigating the action of liquid ammonia on a variety of selenium compounds, Streeker and Claus 5 have come to the conclusion that the tetrahalides are the best initial materials for the preparation of selenium nitride. The action of liquid ammonia on selenium tetra-bromide in the presence of carbon disulphide gives a good yield of the nitride.

For sulphur nitride, see nitrogen sulphide for selenium, nitride, see nitrogen selenide and for tellurium nitride, see nitrogen telluride. J. von Liebig 26 obtained a brown powder by igniting chromium chloride in ammonia, and he thought the product was elemental chromium. A. Schrotter showed that the product is chromium nitride, Cr2N2 or CrN. 

Selenium nitride, SeN, is formed by the reaction of selenium or selenium chlorides Se2Cl2 or SeCLi with active nitrogen prodnced by a high freqnency discharge. To date, only the electron band spectra have been investigated. 

On the basis of vibrational and Se NMR spectra, the hybrid sulfur/selenium nitride SeS3N2 has a cyclic structure in which the selenium atom is linked to two sulfur atoms (62). " ...
