BeH2 is covalent hydride and having polymeric structure in solid state in which beryllium atoms are bonded together by three centre-two electrons(3c-2e) bridge bond which also know as banana bond and all the H-Be-H bond angle are below 109.28’
But in gaseous
BeH2 exist in dimeric form in which Be atoms are sp2 hybridised, planer
and non polar(dipole moment zero).
