Monitoring the Crystal Growth and Interconversion of New Coordination Networks in the Self-assembly of MCl2 Salts (M = Co, Ni, Cu, Cd) and 1,3-Bis(4-pyridyl)propane
Source abstract
Abstract
The combined use of microscopy methods and conventional X-ray crystallography offers new possibilities for the study of the self-assembly of coordination networks. This approach has been applied to the reactions of MCl2 salts (M = Co, Ni, Cu, Cd) and 1,3-bis(4-pyridyl)propane (bpp). Copper gives [Cu(bpp)3Cl2]·2H2O (1), [Cu(bpp)2Cl]Cl·1.5H2O (2), and [Cu(bpp)2Cl2]·2.75H2O (3), that are 1D, 2D, and 3D polymers, respectively. Monitoring of the crystal growth shows that 1 and 2 are formed from the same mixtures in water, but at different times and conditions and can be interconverted (figure). Both 1 and 2 are transformed into 3 when suspended in EtOH.
