在有机金属银（I）超分子配合物聚[[银（I）-μ（3）-3-[4-（2-噻吩基）-2H-环戊二烯并[d]哒嗪-1-基]苯甲腈]高氯酸盐甲醇溶剂化物]{[Ag（C（18）H（11）N（3）S）]（ClO（4））·CH（3）OH}（n）中，只有一种类型的Ag（I）中心位于{AgN（2）Spi}配位环境中。两个不对称的多齿3-[4-（2-噻吩基）-2H-环戊二烯并[d]哒嗪-1-基]苯甲腈（L）配体通过π-Ag（I）相互作用将两个Ag（I）原子连接成有机金属盒状单元，两个3-氰基苯甲酰基臂从该有机金属盒状单元以相反方向延伸并结合来自相邻盒状结构单元的两个Ag（I）原子。这导致在晶体学bc平面中延伸的新颖的二维网络。这些二维薄片沿结晶学a轴沿着堆叠在一起以产生平行四边形状通道。甲醇溶剂分子和高氯酸盐反离子位于通道中，在那里它们通过分子间氢键相互作用固定。这种结构可以为主体-客体化学提供机会，例如客体分子损失和吸收或离子交换。新的富烯型多齿配体L是制备含Cp-Ag（I）（Cp为N）金属有机配位聚合物或超分子配合物的良好候选者。
In the organometallic silver(I) supramolecular complex poly[[silver(I)-mu(3)-3-[4-(2-thienyl)-2H-cyclopenta[d]pyridazin-1-yl]benzonitrile] perchlorate methanol solvate], {[Ag(C(18)H(11)N(3)S)](ClO(4)).CH(3)OH}(n), there is only one type of Ag(I) center, which lies in an {AgN(2)Spi} coordination environment. Two unsymmetric multidentate 3-[4-(2-thienyl)-2H-cyclopenta[d]pyridazin-1-yl]benzonitrile (L) ligands link two Ag(I) atoms through pi-Ag(I) interactions into an organometallic box-like unit, from which two 3-cyanobenzoyl arms stretch out in opposite directions and bind two Ag(I) atoms from neighboring box-like building blocks. This results in a novel two-dimensional network extending in the crystallographic bc plane. These two-dimensional sheets stack together along the crystallographic a axis to generate parallelogram-like channels. The methanol solvent molecules and the perchlorate counter-ions are located in the channels, where they are fixed by intermolecular hydrogen-bonding interactions. This architecture may provide opportunities for host-guest chemistry, such as guest molecule loss and absorption or ion exchange. The new fulvene-type multidentate ligand L is a good candidate for the preparation of Cp-Ag(I)-containing (Cp is cyclopentadienyl) organometallic coordination polymers or supramolecular complexes.
