The reaction of [2.2.2]cryptand, 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo- [8 .8 .8 ]hexacosane, with mercuric thiocyanate yields crystals of [Hg(cryptand 222 )][{Hg(SCN )3 }2]. The compound crystallizes monoclinically, space group C2/c, Z = 4, a = 2478.3(12), b = 1540.4(4), c = 1049.4(3) pm, β = 108.77(3)°. In the cation the mercury atom is 8 -coordinated by six oxygen and two nitrogen atoms with distances Hg -N 220(2) pm and Hg -O 268.8(9) pm (mean value). The polymeric anion consists of infinite chains -Hg -SCN -Hg - with bond distances Hg-S 254.2(4) and Hg-N 257(2) pm. Each Hg atom carries two additional terminal SCN ligands, with a mean Hg-S distance o f 244( 1) pm; the distance from Hg to the N atom of an SCN ligand of a neighbouring Hg atom is 300(2) pm, probably indicating an additional, although weak bonding.
