  CsV3Sb5 kagome lattice holds the promise for manifesting electron
correlation, topology and superconducting. However, by far only three
CsV3Sb5-like kagome materials have been experimentally spotted. In this work,
we enlarge this family of materials to 1386 compounds via element species
substitution, and the further screening process suggests that 28 promising
candidates have superior thermodynamic stability, hence they are highly likely
to be synthesized. Moreover, these compounds possess several identical
electronic structures, and can be categorized into five non-magnetic and three
magnetic groups accordingly. It is our hope that this work can greatly expand
the viable phase space of the CsV3Sb5-like materials for investigating or
tuning the novel quantum phenomena in kagome lattice.
