Ice “0”[^1](^1) is a metastable ice polymorph discovered in the supercooled liquid water by computer simulations.1 According to our Vitrite Database,2 ice 0 consists of two type of fragments; one is #34 fragment of 10 nodes (appeared as fragment “G” in Ref. 2) and the other is #874 fragment of 14 nodes. Their appearance ratio is 1:1. Their network topologies are: (in @NGPH format)

The vitrite #34 is abundant in the supercooled liquid water while the vitrite #874 is very rare. Even the spontaneous clustering of #34 and #874 is not observed in the supercooled liquid.
