✦ Synopsis
A random tetmhcdral n&&k built around liked eight-member rings'is de& than an open one d&crib& earlier. and has neigl~bors nerx in space tha,t UC remoter in bond topology. The propcrtios oFamorphous ice vlc! liquid water below 0°C correlate with a glass transit,ion in an open network at = 140 K, while Linked rings, which increase enthalpy and rfzn- sjty;only appear above about -40°C. i5f ice, ._ While interpenetrating lattices exist in some ices, interpenetrating hexagonal lattices are not possible, nor, apparently, are RTN's with extensive interpene. tration. No report has been made of the possibre degree of interpenetration oFRTN's. The constrictions' 'and properties of.a natworkwith some interpcnetration are reported here. .
