The structure of the (SN) x polymer metal has been redetermined at room temperature by using neutron diffraction on single crystals. It is characterized by endless strands of N and S atoms with equal intrachain distances of d (SN) intra = 1.585 Å. The intrachain bond angles at S and N atoms are 107.0 and 120.3 o, respectively. The shortest interchain distances ( d(SN) inter = 3.26 Å, d(NN) inter = 3.34 Å, and d(SS) inter = 3.47 Å) are in the range of the sum of the van der Waals radii. Besides the N and S sites of the ordinary strands additional defect sites were found.
