Liquid metacrystals with complete 2D symmetry. a, b 2D Bravais LMCs. POM images (a), Scale bars, 100 μm, and insets are single crystal cells; FFT diffraction patterns (b), Scale bars, 1 μm⁻¹. c Two basic grains with vertical (orange) and horizontal (green) configurations. d–g Quasi-crystalline LMCs. POM images (d, f), Scale bars, 500 μm, and insets are rotational repeating cells; FFT diffraction patterns (e, g), Scale bars, 0.2 μm⁻¹. h The radial ACF of a p6mm LMC (inset POM image). i ACF calculated for the p6mm LMC along [100], [010] and [110] planes. j Azimuthal intensity I(Ψ) for FFT spectrum of the 7 m LMC. Yellow plots are experimental data, and blue lines are theoretical peaks for ideal 7 m symmetry group
