✦ Synopsis

In the title compound, rac-Bis ["-(1R,2S,12R,13s,15s,17S,18r)-14,16,19-trioxa-3,7,11-triazatetracyclo[13.3.1.0 2,13 .0 12,17 ]nonadecan-18-olato-1 3 N 3 ,N 7 ,N 11 :2 2 O 18 ]dizinc(II) bis[trichloro-(pyridine)zincate(II)], [Zn 2 (C 13 H 22 N 3 O 4 ) 2 ][ZnCl 3 (C 5 H 4 N)] 2 , the cation displays crystallographic inversion symmetry. The geometry at zinc is trigonal bipyramidal. Three hydrogen bonds NÐHÁ Á ÁClÐZn lead to the formation of columns parallel to the a axis.
