      abstract     = {Transition-metal carbodiimides, with the general formula
                      Mx(NCN)y, are gaining renewed interest due to their
                      excellent electrochemical and photocatalytic
                      properties.[1-2] These quasi-binary compounds can be seen as
                      nitrogen-containing versions of MxOy oxides generated by the
                      isovalent replacement of O2− by the extended carbodiimide
                      −N=C=N− or cyanamide N≡C−N2− dianions. Indeed,
                      their crystal structures show similarities to oxides, with a
                      clear propensity for close-packed anionic arrangements.
                      However, the lower electronegativity of NCN compared to O,
                      along with a greater degree of charge delocalization,
                      results in phases with enhanced covalent character and
                      reduced band gaps.A natural development, therefore, is to
                      expand the range of transition-metal carbodiimides to
                      include ternary and higher-order compounds, which may lead
                      to new or improved properties. In this talk, I will discuss
                      the synthesis of the first non-binary transition-metal
                      carbodiimides, analyse their crystal structures, with the
                      support of DFT calculations, and investigate their diverse
                      physicochemical properties and potential applications.
