Abstract The crystal structures of 1,4,7,10,13,16-hexaoxa-cyclooctadecane dicyano mercury(II) monohydrate, C14H24HgN2O6·H2O, 1, and 2,5,8,11,18,21,24,27-octaoxa-tricyclo[26.4.0.012,17]-dotriconta-1(28),12,14,16,29,31-hexaene dicyano mercury(II) monohydrate, C26H32HgN2O8·H2O, 2, were determined: 1 crystallizes in the trigonal space group R3¯ with cell dimensions a = 11.7842(1) and c = 12.0316(1) Å. 2 crystallizes in the monoclinic space group P21/c with cell dimensions a = 11.156(3) Å, b = 8.417(2), c = 30.901(8) Å, and β = 93.279°. In spite of the different cyclic systems, similar complexes are formed where the Hg atom is coordinated by two CN groups and six oxygen atoms of the crown ether. The structure of 1 is isostructural with the crystal structures of 18C6—HgCl2, 18C6—CdBr2, 18C6—Sr(BH4)2, and 18C6—Ba(BH4)2. Furthermore, 1 is very similar to other 18C6—HgX2 complexes.
