OH−O and CH−O Hydrogen Bonding in Hydrated Crystals of Paramagnetic [(η⁶-C₆H₆)₂Cr]⁺

Abstract

The hydrated crystalline species [(η 6 -C 6 H 6 ) 2 Cr][OH]·3H 2 O and [(η 6 -C 6 H 6 ) 2 Cr][CHD]·3H 2 O (CHD = 1,3-cyclohexanedione) have been prepared and structurally characterized, showing that OH−O as well as CH−O hydrogen bonds involving the water molecules are responsible for crystal cohesion.
