Source of material
5-Chlorosalicylaldehyde (4.69 g, 0.01 mol) was placed in 15 mL ethanol at room temperature, then added into triaminoguanidine hydrochloride (1.40 g, 0.01 mol) solution containing 10 mL water and 8 mL ethanol. The mixture was heated and stirred at 65 °C for 3 h, and finally cooled to room temperature, Then remove the sediment was removed and the obtained filtrate stands for three days to precipitate light pink block crystals.
Experimental details
The crystal data collection was done on a XtaLAB Synergy R, HyPix diffractometer [1]. Using Olex2 [2], the structure was solved with the SHELXT [3] structure solution program and refined with the SHELXL [4] refinement package. All H-atoms were placed geometrically and refined using a riding model with common isotropic displacement factors U iso(H) = 1.2 or 1.5 U eq (parent C-atom).
Comment
As a good building block, triaminoguanidinium chloride and its derivatives are widely used in coordination chemistry [5, 6]. In addition, because triaminoguanidinium chloride contains rich N atoms and has good biological activity, it is also used in the research field of energetic materials [7] and biomedicine [8]. As far as we know, there are four reported structures of salts containing a triaminoguanidine-based Schiff base cation [10], [11], [12], [13]. We synthesized the title compound on the basis of previous studies.
The asymmetric units of the title compound include one [C22H18Cl3N6O3]+ cation, one Cl− anion and three solvent methanol molecules (see the figure). They are connected by O–H⋯Cl and N–H⋯O weak intermolecular hydrogen bonds, which makes the structure of the whole compound more stable. In the title compound, the bond lengths of N2=C2, N4=C9 and N6=C16 are 1.279 (2), 1.279(2) and 1.280(2) Å respectively. They are basically consistent with the reported C=N (1.279 Å) [9] double bond lengths of similar structures. Other bond lengths and bond angles are also within the normal range.
