Highly occupied : A highly porous form of Mg(BH 4 ) 2 (see picture; Mg green, BH 4 blue, unit cells shown in red) reversibly absorbs H 2 , N 2 , and CH 2 Cl 2 . At high pressures, this material transforms into an interpenetrated framework that has 79 % higher density than the other polymorphs. Mg(BH 4 ) 2 can act as a coordination polymer that has many similarities to metal–organic frameworks.
