The crystal structures of three bridged bimetallic mol-ecular compounds, namely, tri-aqua-2κ -μ-fluorido-penta-fluorido-1κ -(1,10-phenanthroline-2κ ,')copper(II)titanium(IV) monohydrate, [Cu(TiF)(phen)(HO)]·HO (phen is 1,10-phenanthroline, CHN), (I), tri-aqua-2κ -μ-fluorido-penta-fluorido-1κ -(1,10-phenanthroline-2κ ,')copper(II)zirconium(IV) monohydrate, [Cu(ZrF)(phen)(HO)]·HO, (II), and tri-aqua-2κ -μ-fluorido-penta-fluorido-1κ -(1,10-phenanthroline-2κ ,')copper(II)hafnium(IV) monohydrate, [Cu(HfF)(phen)(HO)]·HO, (III), and one mol-ecular salt, bis-[diaqua-fluorido-(1,10-phenanthroline-κ ,')copper(II)] hexa-fluorido-hafnate(IV) dihydrate, [CuF(phen)(HO)][HfF]·2HO, (IV), are reported. The bridged bimetallic compounds adopt Λ-shaped configurations, with the octa-hedrally coordinated copper(II) center linked to the fluorinated early transition metal a fluoride linkage. The extended structures of these Λ-shaped compounds are organized through both intra- and inter-molecular hydrogen bonds and inter-molecular π-π stacking. The salt compound [Cu(phen)(HO)F][HfF]·HO displays an isolated square-pyramidal Cu(phen)(HO)F complex linked to other cationic complexes and isolated HfF anions through inter-molecular hydrogen-bonding inter-actions.
报道了三种桥联双金属分子化合物，即三水合二κ-μ-氟代-五氟代-1κ-(1,10-菲咯啉-2κ,')铜(II)钛(IV)一水合物，[Cu(TiF)(phen)(H₂O)]·H₂O（phen为1,10-菲咯啉，C₁₂H₈N₂），(I)；三水合二κ-μ-氟代-五氟代-1κ-(1,10-菲咯啉-2κ,')铜(II)锆(IV)一水合物，[Cu(ZrF)(phen)(H₂O)]·H₂O，(II)；以及三水合二κ-μ-氟代-五氟代-1κ-(1,10-菲咯啉-2κ,')铜(II)铪(IV)一水合物，[Cu(HfF)(phen)(H₂O)]·H₂O，(III)，和一种分子盐，双[二水合氟代-(1,10-菲咯啉-κ,')铜(II)]六氟代铪(IV)二水合物，[CuF(phen)(H₂O)₂][HfF₆]·2H₂O，(IV)。桥联双金属化合物采用Λ形构型，八面体配位的铜(II)中心通过氟桥键与氟化早期过渡金属相连。这些Λ形化合物的扩展结构通过分子内和分子间氢键以及分子间π-π堆积构建而成。盐化合物[Cu(phen)(H₂O)₂F][HfF₆]·H₂O展示了一个孤立的四方锥Cu(phen)(H₂O)₂F配合物，它通过分子间氢键相互作用与其他阳离子配合物和孤立的HfF₆²⁻阴离子相连。
