Fig. 10.12 Crystal structure and chain structure of K 2 (NC 3 N)[Pt 2 (pop) 4 I] 4H 2 O( left ) and
K 2 (NC 3 N)[Pt 2 (pop) 4 I] ( right ). Pt-I and Pt-I-Pt distance are described with the schematic figure.
Hydrogen atoms are omitted for clarity. I(1) and I(2) in K 2 (NC 3 N)[Pt 2 (pop) 4 I]·4H 2 O and K + ions
in K 2 (NC 3 N)[Pt 2 (pop) 4 I] are disordered. Pt yellow ,I purple ,K brown ,P orange , O (ligand) red ,
O(H 2 O) light blue ,N blue ,C black
