Crystalline and Molecular Structure of Hydrated 2,6‐Xylidinium Tetrachlorozincate(II)

Abstract

A new zinc complex compound of formula [2,6-(CH3)2-C6H3NH3]2ZnCl4. 2H2O has been prepared and characterized by X-ray crystallography, thermal analysis and IR spectroscopy. The complex crystallizes in the monoclinic space group P21/a with a minimal tetrahedral distortion of the ZnCl42-ion, a = 7.448(1) Å, b = 38.486(3) Å, c = 8.298(1) Å, β= 112.52(1) °, V = 2197.4(4) Å3and Z = 4. The crystal structure was solved and refined to R = 0.047 with 3270 independent reflections. It can be described by inorganic layers of [ZnCl4.(H2O)2]2-parallel to (010) plane, between which the 2,6-xylidinium cations are located. The grouping is maintained by different types of interactions (electrostatic, H-bonds, Van der Walls and π-π stacking). A characterization of this compound by thermal analysis and IR spectroscopy are also reported.

Crystal structure, Hirshfeld surfaces computational study and physicochemical characterization of the hybrid material (C7H10N)2[SnCl6]·H2O

“…The bands in the [1000-500] cm -1 range can be attributed to the out-of-plane bending modes γ(C aryl -H) andγ(C aryl -C aryl ). All these assignments are in good agreement with that found in the literature [45][46][47][48][49][50]. According to previous works containing the hexachlorostannate anion, the internal vibrational modes of [SnCl 6 ] 2anion appear below 500 cm -1 in IR spectrum [51].…”

“…Indeed, the fact that the Zn-Cl1 bond length is the longest meets the expectation derived from hydrogen bonding effects, because the atom Cl1 accepts three hydrogen bonds, while the remaining Cl2, Cl3 and Cl4 chlorine atoms are doubly acceptors (Table 3 ). However, the mean values of the Zn-Cl bond lengths and Cl-Zn-Cl bond angles are 2.266(5) Ǻ and 109.47(2)°, respectively, are in agreement with those found in 2,6-Xylidinium tetrachlorozincate dihydrate [ 2.267 Ǻ and 109.5°] 22 . In the title hybrid material, the Cl-Zn-Cl angles range from 106.12(2) to 113.86(2)°.…”
