Abstract

Four novel multidimensional coordination polymers, {[Cd(3‐PYD)~2~(H~2~O)]·2H~2~O}~n~ (1), [Pb(3‐PYD)~2~]~n~ (2), {[Cu~1.5~(3‐PYD)~3~(H~2~O)]·1.5H~2~O}~n~ (3) and [Zn(3‐PYD)~2~(H~2~O)~2~]~n~ (4), have been hydrothermally synthesized from 3‐(3‐pyridyl)acrylic acid (3‐HPYD). In 1, 3‐PYD in a head‐to‐head arranged fashion bridges Cd^II^, generating a two‐dimensional layer, which is further extended into a three‐dimensional supramolecular network by hydrogen‐bonding interactions. Compound 2 shows a two‐dimensional wave‐like layer that consists of {Pb(3‐PYD)}~4~ rings from head‐to‐tail arranged 3‐PYD. Compound 3 is a twofold interpenetrating three‐dimensional network consisting of {Cu(3‐PYD)}~6~ rings formed through the mixed head‐to‐head and head‐to‐tail arrangements of 3‐PYD. However, 4 is a three‐dimensional supramolecular framework constructed by one‐dimensional zinc‐3‐PYD chains through hydrogen‐bonding interactions. (© Wiley‐VCH Verlag GmbH & Co.
