| Abstract: | The complex Na2 CrW3O4(O2CCH3)8]2·H2O (Mr = 2343. 80) crystallizes in monoclinic, space group P21/n with a=11. 206 (4 ), b=18. 016 (9), c=14. 465 (5) A, β=98. 00(3)°, V=2891. 9 A, Z=2, Dc=2. 69 g/cm3, F(000) =2168. Final R= 0.043, Rw=0.049 for 3144 independent reflections with I>3σ(I).The complex anion contains two W3O4 core which were connected by two Cr atomsthrough four μ3-O atoms and eight bridging CH3COO- groups. Each of the Cr atomsand the W atoms is coordinated by six oxygen atome. The amons are linked by Na+cations to form one-dimensional infinite chain structure. The infrared spetrum of thecompound has been measured and rationally assigned. |
