• The title inclusion compound, which has a new-type "double decker" host skeleton, has been obtained, and its crystal and molecular structure has been determined by the X-ray diffraction technique using its single crystal. 2-Pyrrolidone molecules are not directly coordinated to any metal atoms, but are hydrogen-bonded with coordinated water-oxygen atoms in the two-dimensional polymer planes of [CoHg(SCN)<SUB>4</SUB>(H<SUB>2</SUB>O)<SUB>2</SUB>]<I>n</I>. In the complex polymer, each pair of adjacent Hg(4S(SCN) four-coordinated in a tetrahedral geometry) and Co(4N(SCN), 2O(water, trans) six-coordinated in an octahedral geometry) atoms are bridged with a thiocyanate (SCN) ion. Such two types of networks are spread approximately parallel to the (010) plane at 1/4 and 3/4 heights, and the included Lewis base molecule layers are also doubled. Compared with the previously reported single-layer host skeleton of [CoHg(SCN)<SUB>4</SUB>(H<SUB>2</SUB>O)<SUB>2</SUB>]·2L (L=Lewis base), the present one is short in its inter-complex layer distance, in spite of the analogous size of the included molecule. The crystallographic data are: orthorhombic, space group <I>P</I>2<SUB>1</SUB><I>nb</I>, <I>a</I>=12.004(4), <I>b</I>=15.330(5), <I>c</I>=11.985(4) Å, and <I>Z</I>=4. The final <I>R</I> value was 0.054.
