Beschreibungen/Notizen

• A mixed lead/tin bromide carbodiimide oxide was synthesized by solid‐state reaction between Pb(CN2), PbBr2, SnBr2 and SnO at 400 °C. Its monoclinic crystal structure was solved and refined in the space group C2/m by single‐crystal X‐ray diffraction from a yellow single crystal. One crystallographic site was found to be occupied by both tin and lead, in agreement with the results of energy‐dispersive X‐ray spectroscopy (EDX). The crystal structure comprises a complex network of tin/lead tetrahedra and tin/lead trigonal bipyramids linked by NCN units. In contrast to Pb(CN2), where the NCN ion is present as a cyanamide moiety, IR‐spectroscopy of the title compound revealed the carbodiimide character of the NCN ion.
