Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Disulfur dinitride is the chemical compound S2N2 with a cyclic square planar structure. Passing gaseous S4N4 over silver metal wool at 250-300°C at low pressure (1mm Hg) yields cyclic S2N2. The S2N2 molecule is virtually square and planar. The S-N bond lengths are 165.1pm and 165.7pm and the bond angles are very close to 90. The S2N2 molecule is isoelectronic with the S42+ and has 6 electrons. The bonding has been investigated using a spin-coupled valence bond method…mehr

The S2N2 molecule is virtually square and planar. The S-N bond lengths are 165.1pm and 165.7pm and the bond angles are very close to 90. The S2N2 molecule is isoelectronic with the S42+ and has 6 electrons. The bonding has been investigated using a spin-coupled valence bond method and is described as having four framework sigma bonds, with the N atoms bearing a high negative charge and the S atoms a corresponding positive charge. Two electrons from the sulfur atoms are coupled across the ring making the molecule overall a singlet diradical.
