N2  - Room-temperature, single-crystal X-ray studies are recorded for the variously hydrated Group 1 metal derivatives of 2-nitrophenol (2-npH = C6H5NO3). A provisional determination is reported for Li(2-np).&frac12;H2O, set as monoclinic, P21/c, a 3&#183;535(3), b 15&#183;06(1), c 24&#183;42(2) &#197;, &#946; 91&#183;7(1)&#176;, Z = 8, conventional R on F currently 0&#183;18 for No 875 &#8216;observed&#8217; (I &#62; 3&#963;(I)) reflections. Na(2-np).H2O is monoclinic, C2/c, a 34 &#183;23(2), b 3&#183;624(4), c 35&#183;48(2) &#197;, &#946; 91&#183;24(4)&#176;, Z = 24, R 0&#183;060 for No 1371. Rb(2-np).&frac12;  H2O is monoclinic, C2/c (isomorphous with the previously determined potassium analogue), a 25&#183;269(9), b 5&#183;381(5), c 12&#183;010(3) &#197;, &#946; 105&#183;35(3)&#176;, Z = 8, R 0&#183;046 for No 1380. Cs(2-np).&frac12;H2O is monoclinic, P21/n, a 7&#183;648(3), b 26&#183;19(1), c 8&#183;713(6) &#197;, &#946; 111&#183;75(2)&#176;, Z = 8, R 0&#183;061 for No 2347. All compounds except the lithium derivative are two-dimensional polymeric sheets in which the aromatic rings project to either side of a core of metal atoms coordinated by a web of 2-nitrophenoxide oxygen atoms in various bridging functionalities. The lithium compound is a novel &#8216;stair&#8217; polymer with two crystallographically independent lithium atoms at successive independent Li&#8211;O crossbars, the oxygen atoms of which are phenoxide-Oof each of the two independent ligands. The lithium atoms are alternately four- and five-coordinate, the fourth coordination site of the first being occupied by the water molecule oxygen atom, while the fourth and fifth sites of the second are occupied by the cis-2-nitro oxygen atoms of the two ligands
