Abstract

Structures of [Cd(C2H8N2)Cl2]n(1) and [Cd(C2H8N2)Br2]n(2) were solved from powder diffraction data. Compound (1) crystallizes in the space group Pbam (No. 55), a = 9.9021(7) Å, b = 7.8186(6) Å, c = 4.0705(3) Å, V = 315.13(3) Å3, Z = 2. (2) is isostructural: space group Pbam (No. 55), a = 10.405(2) Å, b = 7.8634(8) Å, c = 4.2079(5) Å, V = 344.28(6) Å3, Z = 2. The investigated compounds are examples of two-dimensional hybrid coordination polymers, in which neighboring metal centers are bridged via both organic and inorganic moieties: ethylenediamine molecules and halide anions. Both crystal structures were solved ab initio from powder data using direct methods.
