| Abstract: | Complex of 18-crown-6 with K2Pd(NO2)4]has been isolated and characterized by IR and X-ray diffraction analysis. The crystal structure belongs to monoclinic, space group P21/c with cell dimensions, α =1.710 4(3),b=1. 485 9(3),c=1. 576 3(3) nm,β=93.49(3)0,V=3. 998 7(14) nm3,Z=4,F(000)=1 880,In the solid state, the complex contains two groups K (18C6)]2 Pd (NO2)4] (1) and K (18C6) ]2 Pd (NO2)4] (H2O)(2).The later displays an one-dimensional infinite chain of two K(18C6)]+ complex cations and a Pd(NO2)4]2-anion bridged by one H2O molecule between adjacent K(18C6)]+ units. |
