The single crystal structure of (PPN)2 [Fe4S4 (SPh)4]has been determined by X-ray diffraction. The crystal is in the space group P42/n, with two molecules per unit cell.The unit cell dimensions are a=b= 1. 671 0(3) um, c=1. 560 9(4) nm, V=4. 358 8nm3, Z=2, dc = 1. 421 g/cm3. Full-matrix refinement on 2 218 reflection data (I>3σ(I) ) give final R (Rw) value of 0. 069 (0. 031).
