“…This is in line with the obtained IR results. In addition, for the latter complex, the results are compatible with the X-ray structural analysis reported by Antsyshkina et al [23] Element analysis (C, H) was performed for both complexes. Anal.…”

“…This leads to distortion of the crown ring and asymmetric screening of the tin atom. [23,29] On the other hand, [Sn(18-Cr-6)Cl 4 ] possesses a more symmetrical structure with a crown ether, coordinated around the tin cation as a multidentate macrocycle and chlorine atoms, bonded at the top and bottom (we assume that superstoichiometric water plays a minor role in the complex structure, see discussion in Sec. …”

In this article is a report of SnO2 deposition by aerosol‐assisted (AA)CVD from tin complexes, [Sn(18‐Cr‐6)Cl4] and [Sn(H2O)2Cl4](18‐Cr‐6). The structure and properties of the precursors, used to synthesize SnO2 layers by AACVD for the first time, are characterized with the help of X‐ray diffraction (XRD), infrared (IR), and thermogravimetric analysis (TGA). Each complex is deposited by AACVD at 250, 400, and 500 °C in a flow of N2. The resulting films are studied by XRD and atomic force microscopy (AFM). Gas‐sensing properties of the deposited layers are tested to 10 ppm NO2 in air. The maximum sensor response to the analyte is measured at 300 °C.

“…The elongation is presumably due to the higher coordination number of the Sn atoms (CN = 6) and O atoms (CN = 3) of Sn 2 Cl 6 (OEt) 2 (HOEt) 2 . The Sn-Cl bond lengths of 2.343(1), 2.350(1), and 2.3922(9) Å compare well with those observed in the related dimer [Sn 2 Cl 6 (OH) 2 (H 2 O) 2 ] · 4 H 2 O [2.3426(6), 2.3698 (7), and 2.3865(7) Å ] (Shihada et al, 2004) and various 18-crown-6 stabilized SnCl 4 · 2 H 2 O solvates (Junk and Raston, 2004;Antsyshkina et al, 2011). The ethanol molecules are involved in intramolecular hydrogen bridges with adjacent chlorine atoms.…”
