Abstract
Chemical vapor deposition (CVD) precursors often employ fluorinated β-diketonate ligands bonded to metal atoms; however, these are prone to the formation of hydrates under ambient conditions and form hydrogen-bond networks which hinder the CVD process. This work investigated the use of 1,2-dimethoxybenzene (DMB) as a ligand to prevent the formation of hydrogen-bonding networks. The single-crystal structures of two complexes of diaquabis(1,1,1,5,5,5-hexafluoro-4-oxopent-2-en-2-olato-κ2O,O')nickel(II), trans-NiII(hfac)2(H2O)2, were determined, one as a 4/3 hydrate, [Ni(C5HF6O2)2(H2O)2]3·4H2O, and one as a 1,2-dimethoxybenzene (DMB) pentasolvate, [Ni(C5HF6O2)2(H2O)2]·5C8H10O2. The hydrogen-bond networks of these two materials were compared to previously reported hydrogen-bond networks seen in NiII(hfac)2(H2O)2. DMB was found to disrupt the formation of an extended hydrogen-bond network without coordinating to the Ni center.
