MaMorekuru Maumbirwo Demo

Ice ikristaro inoumbwa nekurongeka kwakarongeka kwemamorekuru emvura. Mamorekuru emvura akabatanidzwa nehydrogen zvisungo kuti vagadzire iyo "yakavhurika" (yakaderera-density) yakaoma chimiro. Iyo O-O nzvimbo yenyukireya yekuparadzanisa mamorekuru emvura ari padyo iri 0.276nm, uye iyo O-O-O bond angle ingangoita 109 °, iri padyo padyo nekona kona yetetrahedron yakanaka ye109 ° 28 '. Nekudaro, iyo OO nzvimbo yemamorekuru emvura ayo ari padyo chete asi asina kusunganidzwa zvakananga akakura zvakanyanya, uye iyo yekure-kure iri 0.347 nm. Mamorekuru ega ega emvura anokwanisa kusangana nemamwe mana mamorekuru emvura kuti agadzire tetrahedral mamiriro, saka huwandu hwekubatana kwemamorekuru emvura i4.
