    • Synthesis of (1, An amount of 0.0408 g (0.125 mmol) of In 2S3, 0.051 g (0.15 mmol) of Sb2S3, and 0.016 g (0.5 mmol) of S were combined and loaded in a 3/8 inch Pyrex tube along with 0.30 mL of 1:1 dipropylamine:water in air. The tube was then evacuated to <3 × 10-3 Torr and flame-sealed. The tube was kept in an oven at ∼160 °C for 5 days. The products were isolated in air by filtration and washed with deionized water, ethanol, and ether. The product consists of pale yellow platelike crystals along with some recrystallized Sb2S3 (20, Yield was ∼60, The crystals appear to be stable in air for months.

    • Compound (1) crystal data: The single-crystal X-ray diffraction data was collected with a STOE IPDS diffractometer at 100 K. A platelike crystal with dimensions 0.178 × 0.245 × 0.042 mm3 was chosen for data collection. An analytical absorption correction based on face-indexing was applied. The structure was solved with direct methods using SHELX-97. The PLATON SQUEEZE program was applied to obtain better refinement for the highly disordered organic cations and water molecule.

    • Single-crystal diffraction data was collected at 100 K, and powder XRD was obtained at room temperature; therefore, there is a slight shift to lower 2θ (∼ .32 Å in d-spacing fo the (010) reflection) in the experimental PXRD pattern compared to the calculated one.
