“…For instance, the oxidation of Se 4 N 4 with AsF 5 leads to the cations Se 3 N 2 2+ .and (Se 3 N 2 •+ ) 2 . Se 4 N 4 has also been utilized in the preparation metal complexes of Se 3 N - and Se 2 N 2 2- anions 9 as well as in the synthesis of metal complexes containing a NSeCl ligand …”

The reaction of [(Me(3)Si)(2)N](2)S with equimolar amounts of SCl(2) and SO(2)Cl(2) produces S(4)N(4) in a good yield. The new chalcogen nitride 1,5-Se(2)S(2)N(4) has been prepared in high yield by two different reactions: (a) from [(Me(3)Si)(2)N](2)S and SeCl(4) and (b) from [(Me(3)Si)(2)N](2)Se with equimolar amounts of SCl(2) and SO(2)Cl(2). 1,5-Se(2)S(2)N(4) has a cage structure similar to those of S(4)N(4) and Se(4)N(4). The crystal structure is disordered with site occupation factors ca. 50% for selenium in each chalcogen atom position. The 12 eV EI mass spectrum shows Se(2)SN(2)(+) as the fragment with highest mass. Both the (14)N and (77)Se NMR spectra show a single resonance (-238 and 1418 ppm, respectively). These data rule out the possibility that the crystalline sample is a solid solution of S(4)N(4) and Se(4)N(4) and imply the presence of 1,5-Se(2)S(2)N(4). This deduction was further verified by Raman spectroscopy and vibrational analysis.

“…Several interesting reactions of Se4N4 have been reported recently. [1][2][3][4][5] Without exception these reactions result in breakdown of the heterocyclic ring. For example, the treatment of Se4N4 with [PtC12(PMe2Ph) 12 or Pt(PPh,), produces the complexes Pt(Se3N)C1(PMe2Ph)4 or [Pt(Se2N2)(PPh3)]2,s which contain the chelating ligands Se3N-and Se2N22-, respectively.…”

The reaction of lr5-Ph4P2N4Se2, 1, prepared by the treatment of Ph2PN2(SiMe3)3 with a mixture of SeCI4 and Se2CI2 in acetonitrile, with [PtC12(PEt3)12 gives the adducts [PtCl2(PEt3)],[qI-N-Ph4P2N4Se2] (2, n = 1; 3, n = 2 ) in which the P2N4Se2 ring is shown by an X-ray structural determination of 3 to contain a transannular Se-Se interaction; the oxidative addition of 1 or 2 to Pt(C2H4)(PPh3)2 produces the corresponding q2-Se,Se' complexes.

“…0.1 A out of this plane [N-Se(3)-Pt-P torsion angle 177(1)"]. There is a noticeable difference in the two Pt-Se distancFs with Pt-Se(1) (trans to PMe2Ph) being longer [2.385(2) A] than Pt-Se (3) [trans to C1 2.302(3) A]. Within the PtSe,N ring the two Se-N and the Se-Se bond lengths are in the expected ranges.…”
