Abstract Scope |
Tin-based selenides (SnSe and SnSe<sub>2</sub>) have been explored to be the next generation of flexible materials for electronic, optical, and optoelectronic applications. By introducing a chelating tridentate coordinating (<sup>-</sup>SeEtN(Me)EtSe<sup>-</sup>) ligand system to tin(IV) chloride, air stable and monomeric complexes have been obtained. Variation of the synthetic procedure in similar synthetic routes enabled the isolation of two different tin(IV) complexes [Sn(SeEtN(Me)EtSe)<sub>2</sub>] and [SnCl<sub>2</sub>(SeEtN(Me)EtSe)] which have been characterized by NMR measurements and single crystal XRD. The homoleptic tin compound offers the temperature depending material preparation for both SnSe and SnSe<sub>2</sub>. This has been investigated by detailed thermal decomposition methods and identified by XRD measurements to confirm the phase pure SnSe and SnSe<sub>2</sub> formation. [Sn(SeEtN(Me)EtSe)Cl<sub>2</sub>] offers the possibility to synthesize the heteroleptic complex [Sn(SeN(Me)EtSe)(SEtN(Me)EtS)] to target the synthesis of the ternary SnSSe. This heteroleptic tin(IV) complexe has been investigated by detailed NMR studies as well as by single crystal XRD. |
