Abstract
A new mode of association of water molecules is described. Adamantanoid water clusters bonded to bromide ions as well as other water molecules form a cage within which bromide-encapsulated aza cryptands reside to form a host-within-a-host-like structure. The structure of this adamantanoid water decamer is remarkably similar to that of cubic ice (Ic). The average O···O distance is 2.78 Å, which is close to 2.75 Å present in Ic, and the average O···O···O angle of 109.40Å is also close to the tetrahedral angle in ice Ic.
