| Abstract: | Crystallization of an equimolar mixture of 1,10-dimethylphenanthroline (DMP) and manganese(II) chloride from N,N-dimethylformamide (DMF) has been studied. Rather than a useful route to a well-defined product, it was found that identical solutions could deposit crystals of three different compounds. The most common outcome was the formation of crystals of MnCl2(dmp)(dmf)], 1, or co-crystallization of MnCl2(dmp)(dmf)] and {MnCl2(dmp)}2]. The co-crystals, 2, were always found to dissolve as crystals of 1 started to grow. Crystals of a third compound, MnCl2(dmp)2], 3, were also isolated once. |
