The 1 1 complex with titanium chloride or the 1 2 complex with beryllium chloride may explode violently. Careful pyrolysis of these gives mixtures of disulfur dinitride and its 1 1 complexes with the metal chlorides, which may also explode, so screening is essential.

Solid-state (topochemical) polymerization of cyclic disulfur dinitride to poly(sulfur nitride) (or polythiazyl), -fSN, occurs on standing at ambient temperature or higher [Banister and Gorrell, 1998 Labes et al., 1979 Ray, 1978]. Disulfur dinitride is obtained by sublimation of tetrasulfur tetranitride. Polythiazyl is a potentially useful material, since it behaves like a metal. It has an electrical conductivity at room temperature about the same order of magnitude as a metal like mercury and is a superconductor at 0.3°C. Polythiazyl also has high light reflectivity and good thermal conductivity. However, it is insoluble and infusible, which prevents its practical utilization.

The following procedures give the synthesis of tetrasulfur tetranitride, disulfur dinitride, polymeric sulfur nitride, and tetrasulfur dinitride. 

For the transformation, disulfur dinitride is allowed to stand in a vacuum desiccator for ca. 30 days, after which time all the disulfur dinitride has polymerized to polymeric sulfur nitride. The progress of the reaction may easily be told by the disappearance of the characteristic smell of disulfur dinitride. The product is a dark substance with a metallic luster.

Disulfur dinitride, S2N2, exists as a ring of alternating sulfur and nitrogen atoms. S2N2 polymerizes to polythi-azyl, which acts as a metallic conductor of electricity along the polymer chain. Draw a Lewis structure for... 

Cyclic S-N compounds including S2N2 have been reviewed. An x-ray analysis of disulfur dinitride, S2N2, with alternating sulfur and nitrogen atoms indicates a nearly square planar array with S-N distances of 1.657 and 1.651 A and angles NSN of 89.6° and SNS of 90.4°. The structure of the bis(antimony pentachloride) complex is planar S-N, 1.619 A NSN, 84.9° SNS, 95.1°. An S2N2 complex of copper (II) chloride also is planar S-N, 1.633, 1.641 A N-S-N,...
