Starting materials: butanediamine, PbBr2, HBr
Product: plate-like colorless crystals
Description: 0.34 mmol PbBr2, 0.35 mmol butanediamine are mixed in 3 mL of 9M HBr. The mixture is then heated to 100 ˚C for 2 h to dissolve the solid, and then slowly cooled down to room temperature at −2 °C·hr−1.
Method: Single crystal X-ray diffraction
Description: Frames were collected using Bruker D8 Venture diffractometer equipped with a Photon 100 CMOS detector employing Mo Kα radiation (λ=0.71073 Å).
