| Abstract: | A 1:2 adduct of ZnCl2 with pyridiniopropionate (C5H5N + CH2CH2CO2-,ppBET ) has been prepared and characterized by single-crystal X-ray analysis. The complex crystallizes in the monoclinic space group P21/c(No. 14) with a = 13. 524(2), 6 = 9.322(3), 15. 474(2) A, β=106. 34(2)°, V = 1871. 9(5) A3, Z = 4, Dm = 1. 554gcm-3, Dc=1. 557gcm-3, and μ = 16. 5cm-1. The crystal structure comprises discrete Zn(ppBET)2Cl2] molecules in which the Zn atom is tetrahe-drally coordinated by two unidentate;carboxylato groups Zn - O = 1. 965(4) , 1. 969 (4)A] and two chloro ligands Zn-Cl=2. 269(2),2. 266(1)A]. |
