The Open Lattice of Ice
X-ray studies of ice crystals reveal a highly ordered, three-dimensional, hydrogen-bonded lattice (Fig 9.2). Each oxygen atom sits at the centre of a tetrahedral arrangement of four neighbouring oxygen atoms, each at a distance of 276 pm. …
What this figure shows. A three-dimensional ball-and-stick lattice diagram of hydrogen-bonded ice, drawn in perspective as a roughly diamond/hexagonal open network. Green spheres (legend '= O') represent oxygen atoms and small orange/peach spheres (legend '= H') represent hydrogen atoms, connected by solid lines (covalent O-H bonds) and dotted lines (hydrogen bonds) running between neighbouring water units, forming a wide, open, tetrahedrally-linked cage-like framework with large empty holes between the chains — illustrating the highly ordered, open three-dimensional hydrogen-bonded structure of ice …
