| Abstract: | Synthesis and Characterization of Zn{Si(NMe2)2(NHCMe3)(NCMe3)}(μ‐NC5H4)]2, a Molecular Single Source Precursor for ZnSiN2 For an application as single source precursor for ZnSiN2 the siladiazazinca cyclo butane Zn{Si(NMe2)2(NHCMe3)(NCMe3)}(μ‐NC5H4)]2has been synthesised for the first time from Si(NMe2)2(NLi t‐Butyl)2 and ZnCl2(NC5H5)2. It has been characterized by single crystal structure analysis (P1, a = 870.5(3) pm, b = 903.8(3) pm, c = 1530.6(4) pm, α = 96.982(5)°, β = 106.501(5)°, γ = 104.729(5)°). The CP‐MAS‐NMR data for the nuclei 13C, 15N and 29Si are reported. ZnSiN2 was prepared by thermal decomposition of the precursor molecule and characterized by elemental analysis, EDX, IR spectroscopy and thermal analysis. The crystal structure was determined (X‐ray powder diffraction data, profile matching: P63mc, a = 315.33(1) pm, c = 508.07(2) pm, RB = 4.87). The thermal behaviour of the precursor molecule, the preparation of polymers by linking with NH3 and the decomposition of the polymers in an argon or NH3 stream were investigated. |
