%X Room-temperature single-crystal X-ray studies are recorded for 4-nitrophenoxide (4-np&#175;) salts, variously hydrated, of the Group 1 metals, M(4-np-).&chi;H2O, for M = Li, Na (redetermination), K (already recorded), Rb and Cs. Li(4-np).3H2O is monoclinic, space group Pc, a 11&#183;359(3), b 7&#183;518(3), c 10&#183;855(4) &#197;, &#946; 90&#183;56(3)&#176;, Z = 4; conventional R on &#124;F&#124; was 0&#183;056 for No 2098 independent &grave;observed&quot; (I &#62; 3&#963;(I)) reflections. Na(4-np).2H2O is orthorhombic, Ima2, a 6&#183;888(6), b 19&#183;699(8), c 6&#183;436(8) &#197;, Z = 4, R 0&#183;031 for No 664. Rb(4-np).H2O is orthorhombic, Pbca, a 11&#183;82(3), b 19&#183;724(7), c 7&#183;199(1) &#197;, Z = 8, R 0&#183;036 for No 1465. Cs(4-np).3H2O is monoclinic, P 21/c, a 13&#183;337(2), b 12&#183;770(5), c 6&#183;311(2) &#197;, &#946; 100&#183;56(3)&#176;, Z = 4, R 0&#183;031 for No 2636. Whereas the lithium compound is essentially a discrete mononuclear neutral molecular complex &#91;(4-np-O)Li(OH2)3&#93; with four-coordinate lithium, the other compounds exhibit two- or three-dimensional sheet polymer structures with 4-nitrophenoxide moieties providing O-C6H4-NO2 head-tail connecting motifs between successive metal atoms.
