The title compound [K([2.2]crypt)] 2[HgGe 9](dmf) 1) (1) has been obtained by reaction of elemental mercury with the binary phase of the formal composition K 4Ge 9 in dmf and after addition of [2.2]crypt. The X-ray single crystal analysis shows that 1 contains polymeric 1[HgGe 9] 2- units in which Ge 9 clusters are linked together by mercury atoms. The differences in the structures of 1 and the related compound [K([2.2.2]crypt)] 2[HgGe 9](en) 2 2) 2 are discussed.
