${\mathrm{KV}}_{3}{\mathrm{Sb}}_{5}$ has recently attracted considerable attention due to its low-temperature superconducting properties, which are heralded by a charge-density wave. The apparent presence of very weak magnetism does not result in long-range ordering. An explanation the properties we present invokes higher-order terms vanadium magnetization density and ``hidden order'' Dirac (polar) multipoles. dipole, known as an anapole or toroidal is one family electronic multipoles visible x-ray magnetic neutron diffractions while undetectable with standard laboratory-based techniques. Actually, two viable structures, direct descendants established chemical structure, studied view testing their suitability future experiments. One model structure magnetoelectric restricted linear type, whereas second cannot show effect any type. latter hosts strange entity that true scalar (time-odd), associated our paper fictitious charge distribution purely imaginary. Calculated neutron-scattering amplitudes symmetry-informed expressions Bragg diffraction patterns for models found be distinctly different, fortunately. Likewise, magnetochiral signals derived from scattering amplitudes.
