Synthesis and Single-crystal X-Ray Structure Determination of trans-PF6 (tmc=1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecane)

Reaction of RhCl3*3H2O with one molar equivalent of tmc (1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecane) in refluxing MeOH affords the complex cation (1+).The complex PF6 crystallises in the orthorhombic space group Pnma, with each anion and each cation lying on a crystallographic mirror plane.The single-crystal X-ray structure of the octahedral complex shows the chloride ions mutually trans to one another, Rh-Cl 2.355(3) and 2.362(3) Angstroem, with the tetra-aza macrocycle adopting an RRSS conformation with two methyl groups lying above, and two methyl groups lying below the RhN4 plane . trans-(1+) shows a quasi-reversible RhIII-RhII redox couple at E1/2=-0.99 V vs. -(1+) in MeCN; slow loss of chloride occurs on electrochemical reduction of the complex.
