5-dimethylpyrazol-1-yl)pyridazine (ppdMe) were synthesized and were made to react with Cu(I) centers in the presence of different counteranions. Different [2 x 2] metallic grids were obtained. With ligands bpzpm, bpz*pm, and Mebpzpm, a new type of grid was obtained where the facing ligands were divergent and two counteranions (BF(4-) or PF(6-)) were hosted in the resulting cavities and exhibit C-H...F and anion
配体4,6-双(吡唑-1-基)嘧啶(bpzpm),4,6-双(3,5-二甲基吡唑-1-基)嘧啶(bpz(*)pm),4,6-双(合成了4-甲基吡唑-1-基)嘧啶(Mebpzpm)和3,6-双(3,5-二甲基吡唑-1-基)哒嗪(ppdMe)并使其在存在下与Cu(I)中心反应不同的抗衡离子。获得了不同的[2 x 2]金属网格。使用配体bpzpm,bpz * pm和Mebpzpm,获得了一种新型的网格,其中面对的配体发散,并且两个抗衡离子(BF(4-)或PF(6-))容纳在生成的腔中并显示CH。 .F和阴离子... pi处于固态相互作用。吡唑基环上甲基的存在引起结构中的几种变形。在与配体ppdMe形成的络合物中,在网格中发现了两组平行配体,而且产生的空腔较小。抗衡阴离子位于网格外部,并且面对的配体表现出芳族pi-pi堆积相互作用。发现涉及哒嗪环的阴离子-pi相互作用。通过紫外可见光谱和核磁共振波
