In ice each water molecule is surrounded by 4 water molecules placing one in the center and other 4 in the vertices of a tetrahedron. This pattern is extended. In this way ice crystal is formed. Due to the particular geometrical shape there are enough blank spaces among the water molecules. So, water is denser than ice.
