a Pb3S2Cl2 NCs as synthesized (left) and after the accretion process (right). b HAADF-STEM image of a Pb3S2Cl2 NC. c [010] projection of the Pb3S2Cl2 reciprocal lattice measured by 3D-ED, together with a representation of the reciprocal lattice axes and unit cell. d XRPD (top) and PDF (bottom) fits obtained by refining the Pb3S2Cl2 structure in the Cc space group (experimental data = blue, fit curves = orange, residuals = gray). The XRPD profiles are plotted in the Cu-Kα 2θ scale to ease the comparison with lab-grade diffraction patterns. e Two views of the Cc monoclinic Pb3S2Cl2 structure are shown along the high symmetry directions of the corresponding pseudocubic cell ([100] top, [111] bottom). A projection of the monoclinic cell is overlaid in blue, and the directions of the corresponding lattice vectors are indicated by labeled arrows. Atoms color code: Pb = gray; S = yellow; Cl = green. Source data for d are provided as a Source Data file.
