The possibility of controlling the formation of copper (II) coordination polymers based on the
rigid carboxylate ligand 1, 3, 5-benzenetricarboxylic acid (H3btc) and an N, N-divergent
spacer with conformational flexibility, bis (4-pyridylthio) methane (SCS), was investigated.
The new coordination polymers 1∞[Cu (H2btc) 2 (SCS)](1) and 2∞[Cu (Hbtc)(SCS) 2]· H2O
(2) have been prepared and characterized. Compounds 1 and 2 were obtained as a mixture
and optimization of the synthetic conditions allowed the isolation of pure phases in high …

The possibility of controlling the formation of copper(II) coordination polymers based on the rigid carboxylate ligand 1,3,5-benzenetricarboxylic acid (H3btc) and an N,N-divergent spacer with conformational flexibility, bis(4-pyridylthio)methane (SCS), was investigated. The new coordination polymers 1∞[Cu(H2btc)2(SCS)] (1) and 2∞[Cu(Hbtc)(SCS)2]·H2O (2) have been prepared and characterized. Compounds 1 and 2 were obtained as a mixture and optimization of the synthetic conditions allowed the isolation of pure phases in high yield. Topological analysis showed the interpenetration of three networks with a vcm-type topology in 2. The thermal stability and the structural dynamics of these systems have also been investigated.
