| Abstract |
The title salt, [Zn(C2N2H8)(3)](2)[CdI4]I-2, conventionally abbreviated [ Zn( en) 3] 2[ CdI4] I2, where en is ethylenediamine, contains discrete [Zn(en)(3)](2+) cations and [CdI4](2-) anions with distorted octahedral and nearly tetrahedral geometries, respectively, as well as uncoordinated I- ions. The cation and the free I- anion lie on twofold rotation axes and the [CdI4](2-) anion lies on a (4) over bar axis in the space group I (4) over bar 2d. The structure exhibits numerous weak inter-ionic hydrogen bonds of two types, viz. N-(HI-)-I-...(free ion) and N-H-... I([CdI4](2-)), which support the resulting three-dimensional framework. |
