Resumen

The addition of water to a chloroform solution of the Cu6 trigonal prism complex [Cu66F)(μ2OH) (μ3OCH3)22OCH 3)2(3,5-Me2pz)6] (1) (3,5-Me 2pz- = 3,5-dimethylpyrazolate) results in the formation of the Cu6 planar hexagonal ring complex [Cu62OH)6(3,5-Me2pz)6]·CH 3CN·CHCl3 (2). A simple mechanism for this structural re-arrangement is proposed, in which 2 can be viewed as a hydrolysis product of 1. This process is clearly noticeable in the magnetic properties, which change from spin frustrated with a weak antiferromagnetic coupling in 1, to strongly antiferromagnetic in 2. Interestingly, the hexagonal ring complex 2 self-assembles in the solid state to form a porous hexagonal tubular structure containing guest solvent molecules that can be removed and CO 2-exchanged without loss of crystallinity.
