以三种二氰基苯衍生物为桥联配体，合成了四种铜（I）配位聚合物[Cu（dchq）2]（ClO 4）（Me 2CO）2（1; dchq = 1，2-二氰基氢醌），[Cu（ipn）2]（PF 6）（Me 2CO）（2; ipn = 1，3-二氰基苯）和[Cu（dmtpn）2]（X）（dmtpn）（THF）（3a（X = BF 4），3b（X = ClO 4）; dmtpn = 2，5-二甲基苯甲腈）的合成和表征。单晶X-射线分析表明，所有的铜（I）离子在这些配合物具有四面体的几何形状，并通过四个配体也协调到下一个铜离子，导致在形成的配位聚合物化合物。1的聚合物骨架由一维链组成，这些链沿着a轴方向延伸，并通过dchq分子之间的π-π相互作用和通过氢键相互作用而发生弱相互作用。2具有二维薄片，其具有铜（I）离子的正方形排列。正方形晶格在c轴方向上的堆叠形成空腔，其中丙酮分子和PF 6-氨基在空腔中。
With the use of three dicyanobenzene derivatives as bridging ligands, four copper(I) coordination polymers, [Cu(dchq)2](ClO4)(Me2CO)2 (1; dchq = 1,2-dicyanohydroquinone), [Cu(ipn)2](PF6)(Me2CO) (2; ipn = 1,3-dicyanobenzene), and [Cu(dmtpn)2](X)(dmtpn)(THF) (3a (X = BF4), 3b (X = ClO4); dmtpn = 2,5-dimethylterephthalonitrile) were synthesized and characterized. Single-crystal X-ray analyses revealed that all copper(I) ions in these complexes have tetrahedral geometry and are coordinated by four ligands which also coordinate to the next copper ions, resulting in the formation of coordination polymer compounds. The polymer framework of 1 consists of one-dimensional chains that run along the a-axis direction and weakly interact with each other through π−π interactions between the dchq molecules and through hydrogen bonding. 2 has a two-dimensional sheet with a square arrangement of copper(I) ions. Stacking of the square lattice in the c-axis direction forms cavities in which the acetone molecules and PF6- ani...
