Bilayer hydrated Na{sub 0.35}CoO{sub 2}.1.3H{sub 2}O structure has re-directed superconductivity research in recent years. Here, we develop a low temperature synthesis method to prepare a novel hydrous Cs{sub 0.2}CoO{sub 2}.0.63H{sub 2}O compound in one step. The bilayer-hydrate of Cs{sub 0.2}CoO{sub 2}.0.63H{sub 2}O with a greatest interlayer spacing d=10.0(2) A among alkali cobalt oxides has been grown in crystal form. Magnetic susceptibility measurement of Cs{sub 0.2}CoO{sub 2}.0.63H{sub 2}O displays a paramagnetic behavior down to 1.9 K. With the assistance of low temperature molten CsOH solvent, crystals of Rb{sub 0.30}CoO{sub 2}.0.36H{sub 2}O and K{sub 0.35}CoO{sub 2}.0.4H{sub 2}O can be grown. The results provide the capability for preparing a novel hydrous structure and the systematic investigation of interlayer coupling effect of alkali ion insertion compounds. - Graphical abstract: BLH Cs{sub 0.2}CoO{sub 2}.0.63H{sub 2}O crystals grown from low temperature molten salt.
