| Abstract: | Na (N- (p-chlorophenyl ) aza-15--crown--5 ) (Et2O )]2 (Na2W0.5 Mo7.5 O26), Mr= 2119. 4, monoclinic, space group P21/c, a= 17. 803(4), b= 13. 674 (3), c= 14. 610(3), β= 112. 33(3)°, V=3290(1) A3, Z= 2, Dc= 2. 139 g/cm3, μ= 1.704 mm-1, F (000) = 2079, R = 0. 026, Rw= 0. 030. The supermolecular complexconsists of one Na2W0.5Mo7.5O28)2- anion in which only two Mo atoms are replaced byW in 25% (M= l/4W+3/4Mo) and the two Na+ are linked symmetrically to neighbouring W0.5Mo7.5O26]4- units on the right and the left respectively and two complexcanons in which each Na+ deviates from the plane of the four ether oxygens and is coordinated to every hetero--atom in the crownether ring, and is also coordinated to the Oatom of Et2O. |
