We introduce a new unsymmetric ligand, PDIpCy (PDI = pyridyldiimine; Cy = cyclam), that offers two distinct, noncoupled coordination sites. A series of homo- and heterobimetallic complexes, [Zn2(PDIpCy)(THF)(OTf)4] (1; THF = tetrahydrofuran and OTf = triflate), [Ni2(PDIpCy)(THF)(OTf)2](OTf)2 (2), and [NiZn(PDIpCy)(THF)(OTf)4] (3), are described. The one-electron-reduced compounds, [Zn2(PDIpCy)(OTF)3] (4), [Ni2(PDIpCy)(OTf)](OTf)2 (5), and [NiZn(PDIpCy)(OTf)3] (6), were isolated, and their electronic structures were characterized. The reduced compounds are charge-separated species, with electron storage at either the PDI ligand (4) or at the PDI-bound metal ion (5 and 6).

非耦合的同金属和异双金属配合物的非对称配体框架
我们引入了一种新的不对称配体PDIpCy(PDI =吡啶基二亚胺; Cy = cyclam),它提供了两个不同的,非偶联的配位点。一系列均金属和异金属双金属配合物,[Zn 2(PDIpCy)(THF)(OTf)4 ](1 ; THF =四氢呋喃,OTf =三氟甲磺酸盐),[Ni 2(PDIpCy)(THF)(OTf)2 ](描述了OTf)2(2)和[NiZn(PDIpCy)(THF)(OTf)4 ](3)。单电子还原化合物[Zn 2(PDIpCy)(OTF)3 ](4),[Ni 2(PDIpCy)(OTf)](OTf)2(5)和[NiZn(PDIpCy)(OTf)3 ](6)被分离,并对其电子结构进行了表征。还原的化合物是电荷分离的物质,具有在PDI配体(4)或与PDI结合的金属离子(5和6)处的电子存储。
