Coordination chemistry of cis,trans-1,3,5-Triaminocyclohexane : from mononuclear complexes to supramolecular architectures
The coordination chemistry of the rigid, aliphatic triamino ligand \(cis,trans\)-1,3,5-triaminocyclohexane (\(trans\)-tach) is investigated. With closed shell transition metals, \(trans\)-tach forms 1-D {Ag(OTf), ZnCl\(_2\)} networks and a 3-D {AgNO\(_3\)} coordination polymer with unprecedented …

The chemistry of zinc hydrides.
… intramolecular steric effects allowed this, to polymers where intramolecular coordination bonds could not be formed e.g. [m-Me[2]NC[6]H[4]OZnH][n]. Several unusual complex zinc hydrides were obtained, where the reacting substrate appeared to undergo condensation before reacting with the zinc …
