|Title:||Influence of the C=O⋯π interaction on the thermal dehydration behavior of [Cu2(sgly)2(H2O)]·1H 2O||Authors:||Yang, X.
|Issue Date:||Jan-2005||Citation:||Yang, X., Wu, D., Ranford, J.D., Vittal, J.J. (2005-01). Influence of the C=O⋯π interaction on the thermal dehydration behavior of [Cu2(sgly)2(H2O)]·1H 2O. Crystal Growth and Design 5 (1) : 41-43. ScholarBank@NUS Repository. https://doi.org/10.1021/cg0498406||Abstract:||The hydrogen-bonding pattern present in [Cu2(sgly) 2(H2O)]·H2O [1; H2sgly = N-(2-hydroxybenzyl)glycine] has been found to be very similar to that observed in [Cu2(sala)2(H2O)] (2), which undergoes solid state transformation from a hydrogen-bonded one-dimensional helical coordination polymeric structure to a three-dimensional (3D) coordination polymeric network structure with chiral channels, after losing all of the water molecules below 110°C. However, 1 fails to undergo such a transformation when dehydrated thermally. Furthermore, the intermolecular hydrogen bonds in 1 are weaker than those found in 2. A detailed crystal structure analysis of 1 reveals that the presence of the C=O⋯π intermolecular interaction between a carboxylate carbonyl group and a phenyl ring appears to be responsible for the weakening of hydrogen bonds, thermal dehydration behavior, preventing the formation of new Cu-O bonds and, hence, the 3D coordination polymeric network structure.||Source Title:||Crystal Growth and Design||URI:||http://scholarbank.nus.edu.sg/handle/10635/95474||ISSN:||15287483||DOI:||10.1021/cg0498406|
