  Broad-band dielectric spectroscopy, heat capacity measurements and molecular
dynamic simulations are applied to study excitations of interacting electric
dipoles spatially arranged in a network with an inter-dipole distance of 5-10
A. The dipoles with magnitude of 1.85 Debye are represented by single H2O
molecules located in voids (0.5 nm size) formed by ions of the crystal lattice
of cordierite. We discover emergence of nontrivial disordered paraelectric
phase of dipolar system with signs of phase transition below 3 K.
