I. INTRODUCTION

Monomenthyl succinate, C14H24O4 (Figure 1), systematic name 4-[(1R,2S,5R)-2-isopropyl-5-methylcyclohexyl]oxy-4-oxobutanoic acid, is essentially tasteless and provides a good balance of cooling onset and length of cooling (Erman, Reference Erman2007). The CAS register number of the compound is 77341-67-4. Monomenthyl succinate is a safe and innocuous additive of mint, so it is widely used in food products, and it has FEMA (Flavor and Extract Manufacture's Association) GRAS (generally recognized as safe) status (Marin and Schippa, Reference Marin and Schippa2006).

Presently, the crystal structure of monomenthyl succinate by single-crystal diffraction or powder diffraction has not been reported in the literature.

II. EXPERIMENTAL

A. Sample preparation

The title compound (purity: 98%) was purchased from J&K Chemical Co., Ltd. (Beijing, China). It was ground into powder (ρ = 1.06 g cm−3, T melt = 61–63 °C), sieved through a 300-mesh screen, and then mounted on a flat zero background plate. The structure of the compound was characterized by the Fourier transform infrared spectroscopy (FTIR) (Figure S1) and elemental analysis. The elemental analysis showed that the content of C, H, and O were 65.75, 10.39, and 23.86, respectively. The measured FTIR spectrum is consistent with the presumed structure of monomenthyl succinate (Figure 1).

B. Diffraction data collection and reduction

The diffraction pattern for the title compound was collected by an X'Pert PRO diffractometer (PANalytical Co., Ltd., Netherlands) with an X'celerator detector and CuKα 1 radiation (λ = 1.54056 Å, generator setting: 40 kV and 40 mA). The diffractometer was operated in the angular range from 4° to 50°2θ with a step size of 0.01313°2θ and a counting time of 30 ms step−1. The measurement was performed at room temperature and a controlled relative humidity level of 60%. Data evaluation was performed using the Reflex module in the software package Material Studio 4.2 (Accelrys Co., Ltd., USA), which we used to successfully solve the organic crystal structures such as norandrostenedione (Tang et al., Reference Tang, Wu, Pan, Zhang, Cheng and Li2013), levetiracetam (Xu et al., Reference Xu, Liang, Wu, Zhang, Tang and Li2013), and meloxicam (Wu et al., Reference Wu, Tang, Li, Zhang and Li2014).

Automatic indexing was carried out using peak positions obtained from the powder diffraction profiles by the X-Cell method (Neumann, Reference Neumann2003). Then the best indexing results 414 for the value of figure of merit were refined using the Pawley method (Pan et al., Reference Pan, Guo, Duan, Cheng and Li2012) resulting in final R wp of the structure was converged at 8.56%.

III. RESULTS

The calculated density is 1.05 g cm−3, which coincides well with the experimental result (1.06 g cm−3). Besides, the elemental compositions calculated for monomenthyl succinate are C: 65.63, H: 9.38, and O: 24.99%, respectively, which are in good agreement with the experimental values and confirmed the high purity.

The experimental X-ray powder diffraction (XRD) pattern is depicted in Figure 2. Indexing results confirmed that monomenthyl succinate is orthorhombic with space group Pba2, and unit-cell parameters after Pawley refinement are a = 19.352(2), b = 30.015(1), c = 5.277(0) Å, α = β = γ = 90°, unit-cell volume V = 3065.1(6) Å3, and Z = 8. Table I gives the 2θ, d-spacing, relative intensity, and hkl for each observed line. All lines were indexed and are consistent with the Pba2 space group.
