离子标题络合物[MgBr(Thf)5][Co(Dpbz)2]·2THF[THF是四氢呋喃，C4H8O；DPBZ是1，2-二(二苯基膦)苯，C30H24P2]的结构表征表明，阳离子和阴离子与两个四氢呋喃溶剂分子通过弱的C-H⋯O键相互作用而形成共晶。钴中心的几何构型是假四面体，正如D10金属中心的预期那样，只是由于双齿膦配体的限制咬合角而偏离了理想的四面体几何构型。阳离子的三个四氢呋喃配体和一个共晶四氢呋喃溶剂分子在两个方向上都是无序的。在扩展结构中，阳离子和四氢呋喃溶剂分子排列在与阴离子层交替的(100)片状中，后者表现出各种π-相互作用，这可能解释了特殊的堆积排列。
Structural characterization of the ionic title complex, [MgBr(THF)5][Co(dpbz)2]·2THF [THF is tetrahydrofuran, C4H8O; dpbz is 1,2-bis(diphenylphosphanyl)benzene, C30H24P2], revealed a well-separated cation and anion co-crystallized with two THF solvent molecules that interact with the cation via weak C—H⋯O contacts. The geometry about the cobalt center is pseudotetrahedral, as is expected for a d10 metal center, only deviating from an ideal tetrahedral geometry because of the restrictive bite angles of the bidentate phosphane ligands. Three THF ligands of the cation and one co-crystallized THF solvent molecule are each disordered over two orientations. In the extended structure, the cations and THF solvent molecules are arranged in (100) sheets that alternate with layers of anions, the latter of which show various π-interactions, which may explain the particular packing arrangement.
