Fourteen different structures of water hexamer found ab initio within a 6-311G** basis set in the interval of 1.7 kcal/mol above the global minimum represent an unprecedently wide range of conformational plasticity of liquid water. The present work also provides the first ab initio demonstration of the existence of pentacoordinated water clusters.

Key words: liquid water, H-bond pattern, orientational defect, water cluster, 'Dangling' bond, Ab initio HF 6-311** calculation
