WebbSlow evaporation of a multi-solvent system - the same as above, however as the solvent composition changes due to evaporation of the more volatile solvent. The compound is more soluble in the volatile solvent, and so the compound becomes increasingly insoluble in solution and crystallizes. WebbAvoid highly volatile solvents, CH 2 Cl 2 and diethyl ether. Unfortunately, these often work very well. They also tend to lead to creation of crystals by slow evaporation. Avoid long alkyl chains in the solvent, these cause disorder in the lattice if solvent is trapped in
WebbABSTRACT A novel complex, [Mn(C6H12N4)2(H2O)4][Mn(H2O)6][SO4]2·6H2O, was synthesized and hexagonal single crystals with centimeter-scale sizes were obtained by the method of solvent evaporation. It was characterized by elemental analysis, infrared spectrum, thermogravimetric analysis and X-ray single-crystal diffraction.
