pack in an ABCABC... fashion with PF6– anions located in between. Reaction of 1 with a stoichiometric amount of perrhenate ion afforded blue plates of [(CuCl)3L](PF6)(ReO4)2·3H2O (2). Compound 2 has the same lattice structure as 1, but the tricopper unit backbone now traps one ReO4– anion through Coulombic interactions. In addition, three molecules of 2 are bridged by a perrhenate ion, forming a Cu3(μ3-ReO4)
我们描述了一种多齿三脚架配体,其中三个带有二(2-吡啶甲基)胺单元的侧链臂连接到三(邻-二甲苯基)支架的邻位,从而提供N(CH 2 - o -C 6 H 4 CH 2 N(CH 2 py)2)3(L)。在六氟磷酸根阴离子存在下,L与CuCl 2反应,得到[[CuCl)3 L ](PF 6)3 ·5H 2 O(1)的蓝色立方体。1的晶体学研究揭示了三个与对称相关的臂各自协调一个Cu II Cl}单元,两个1的分子通过Cu(μ-Cl)2 Cu桥相互连接,从而扩展了分子结构以形成二维(2-D)层。这些二维层以ABCABC ...的形式包装,其中有PF 6 –阴离子位于两者之间。1与化学计算量的高r酸根离子反应,得到蓝板[(CuCl)3 L ](PF 6)(ReO 4)2 ·3H 2 O(2)。化合物2具有与1相同的晶格结构,但tricopper单元骨干现在捕获一个REO 4 -阴离子通过库仑相

phosphate-metabolizing trimetallic centers in biology were prepared. Four such compounds, [(Cu(II)Cl)3(HPO4)L1](PF6) (1), [(Cu(II)Cl)3(HAsO4)L1](PF6) (2), Na2[Mn(III)6Mn(II)2(H2O)2(HPO4)6(PO4)4(L1)2] (3), and [Co(II)3(H2PO4)Cl2(MeCN)L2](PF6)3 (4), all containing three metal centers bound to a central phosphate or arsenate unit bridging oxygen atoms, have been synthesized and structurally characterized.
