A family of 12 zinc(II) thioureide complexes, of the general form [{L}ZnMe], [{L}Zn{N(SiMe3)2}], and [{L}2Zn], have been synthesized by direct reaction of the thiourea pro-ligands iPrN(H)CS(NMe2) H[L1], CyN(H)CS(NMe2) H[L3], tBuN(H)CS(NMe2) H[L2], and MesN(H)CS(NMe2) H[L4] with either ZnMe2 (1:1) or Zn{N(SiMe3)2}2 (1:1 and 2:1) and characterized by elemental anal., NMR spectroscopy, and TGA. The mol. structures of complexes [{L1}ZnMe]2 (1), [{L2}ZnMe]2 (2), [{L3}ZnMe]鈭?/sub> (3), [{L4}ZnMe]2 (4), [{L1}Zn{N(SiMe3)2}]2 (5), [{L2}Zn{N(SiMe3)2}]2 (6), [{L3}Zn{N(SiMe3)2}]2 (7), [{L4}Zn{N(SiMe3)2}]2 (8), [{L1}2Zn]2 (9), and [{L4}2Zn]2 (12) have been unambiguously determined using single crystal x-ray diffraction studies. TGA has been used to assess the viability of 1–12 as single source precursors for the formation of ZnS. On the basis of TGA data compound 9 was investigated for its utility as a single source precursor to deposit ZnS films on silica-coated glass and crystalline silicon substrates at 150, 200, 250, and 300掳 using an aerosol assisted CVD (AACVD) method. The resultant films are hexagonal-ZnS by Raman spectroscopy and PXRD, and the surface morphologies were examined by SEM and AFM anal. Thin films deposited from (9) at 250 and 300掳 are comprised of more densely packed and more highly crystalline ZnS than films deposited at lower temperatures The electronic properties of the ZnS thin films were deduced by UV-visible spectroscopy to be very similar and displayed absorption behavior and band gap (Eg = 3.711-3.772 eV) values between those expected for bulk cubic-ZnS (Eg = 3.54 eV) and hexagonal-ZnS (Eg = 3.91 eV). This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Computed Properties of C4H7NS).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C4H7NS
