Abstract: Where as numerous partially azide-substituted titanium compounds had previously been reported, 1-7 no binary titanium azides were known. In a recent theoretical study the group 4 metal tetrazides M(N3)4 (M = Ti, Zr, Hf, Th) were predicted 8 to be vibrationally stable exhibiting tetrahedral structures with unique linear M-N-NN bond angles (see Figure 1). All previously characterized covalent binary azide species possess bent M-N-NN angles. In this paper we wish to report the synthesis, isolation and characterization of the first binary titanium azide species Ti(N3)4, Ti(N3)4, Ti(N3)5- and Ti(N3)62-, and provide explanations for the observed and predicted Ti-N-NN bond angles.
