Bound in chains : The molecular Ag 0 chain [Ag 4 py 2 ] n (py=C 5 H 5 N) is formed from two covalently linked infinite zigzag chains of Ag, in which AgAg bonds alternate between long and short (see picture; blue Ag, gray C, orange N). Theoretical calculations indicate that partially positively (+0.35) and negatively (−0.30) charged Ag atoms are alternately located along the chain, which has a bandgap of 4.1 eV.
