Source of material

2-(Dimethylamino)ethanol (1.78 g, 20 mmol) and 1,3-dibromopropane (2.02 g, 10 mmol) were mixed in 5 mL N,N-dimethylformamide. The mixture was stirred for 5 h at 333 K (monitored by TLC). After added into 10 mL diethyl ether, the mixture was kept at 253 K about 4 hours, and then filtrated. The residue was recrystallized from methanol/diethyl ether (1:2, v/v) to afford the white crystals. Yield: 85%.

Experimental details

All H atoms were placed in idealized positions and treated as riding on their parent atoms, with d(C—H) = 0.97 Å (methylene) and Uiso(H) = 1.2Ueq(C); d(C—H) = 0.96 Å (methyl) and Uiso(H) = 1.5Ueq(C); d(O—H) = 0.82 Å (OH) and Uiso(H) = 1.5Ueq(O).

Comment

Due to the antibacterial activities, quaternary ammonium salts (QASs) were used for disinfectants, antiseptics and a variety of clinical purposes such as preoperative disinfection of unbroken skin, application to mucous membranes, and disinfection of noncritical surfaces [4], [5]. For example, alkyl-QAS, dialkyl-QAS, QAS-iodine and QAS-chitosan have received increasing attention due to their vital antibacterial activities [6], [7], [8]. Most of these disinfectants are mono-QASs [9], [10], [11], [12]. However, recent studies have reported that the increased tolerance and decreased sensitivity of bacteria to limit the use of mono-QAS products. Therefore, the development of double-QASs with improving antibacterial activities has important research value. In this paper, 2-(dimethylamino)ethanol has been selected as activity donors to construct novel double-QAS because 2-(dimethylamino)ethanol contains a flexible hydroxyl group. Based on the literature reports, the double-QAS was used as a bridging organic ligand to construct coordination polymers [13], [14]. Herein, it is expected that the double-QAS with two flexible hydroxyl groups can pass through cell membrane into the cell to passivate enzyme and damage bacteria [15], [16], [17].

There are two QAS molecules in the asymmetric unit of the title crystal structure (cf. the figure). Bond lengths and angles are all in the expected ranges. Single-crystal structure analysis reveals that configurations of two QAS molecules are different. In a molecule, two ethoxy groups adopt the cis-configuration compared with central 1,3-propane diamine group. The QAS molecule looks like an ‘U’ type. In another molecule, two ethoxy groups adopt the trans-configuration and it looks like an ‘S’ type. This flexibility of the double-QAS is easier to pass through cell membrane into the cell [18], [19].

The asymmetric unit (two dications and four bromide anions) of the title crystal structrue is shown in the figure. Bond lengths and angels are in the expected ranges [14].
