چکیده
The complexation of copper(II) perchlorate with cis,trans-1,3,5-triamino-cyclohexane (transtachH) yields four related mononuclear complexes, [Cu(trans-tachH)2](ClO4)4·(H2O) (1), [Cu(transtachH)2](ClO4)4·2MeOH (2), [Cu(trans-tachH)2(ClO4)](ClO4)3 (3) and [Cu(trans-tach)(transtachH)(ClO4)2](ClO4)·H2O (4). These complexes only differ with respect to ligand protonation, solvent coordination / content, and counterion binding, yet these small differences manifest as vast differences in the supramolecular structures, and we also show that certain crystalline phases of these four compounds persist for different lengths of time in the mother liquor.
