Abstract
An X-ray crystal study of [Mn(3,5,Cl-salen)(H2O)(2)](2)(ClO4)(2) [3,5, Cl-salen = N,N'-3,5-dichloro(salicylidene)1,2-diaminoethane] reveals i t to be a hydrogen-bonded di-aquabridged dimer; a combination of the s teric bulk of the ligand and a hydrogen bonding system creates a coord ination cleft which can allow the approach of p-benzoquinone and water photolysis to occur on irradiation with visible light (no such photol ysis occurs when sterically bulky 2,5-tert-butyl-p-benzoquinone is emp loyed).
