Figure 3 Ball-and-stick representation for (I) showing the interconnection of Zn-(2-MeIm)-Zn dimers (marked as differently colored polyhedra) by (BTC)3− ions and thus forming a layered arrangement in the b,c plane. Zn: purple, O: grey, N: blue, C: black and H: green. Hydrogen atoms of (BTC)3− are omitted for clarity. |
