suitable for single-crystal X-ray diffraction (XRD). Attempts to prepare the known compound As[S2CN(CH2)5]3 using a similar route resulted in a mixture of As[S2CN(CH2)5]3 and the mixed iodide species As[S2CN(CH2)5]2I. Single-crystals of both compounds were isolated from concentrated Et2O/CHCl3 solutions and their structures are described here for the first time. [PPh4][S2CNR2] salts were prepared for comparison
