Hirshfeld analysis showed that the O…H, C…H, Cl…H (except TP3COOH and 2), N…H and π‐π stacking interactions are the most important intermolecular contacts. The π‐π stacking interactions are the maximum for TP3COOH and complex 6 with net C…C/C…N contacts of 19.4% and 15.4%, respectively. The orbital–orbital interaction energies of the Cu‐N/Cu‐Cl bonds correlated inversely with the corresponding Cu‐N/Cu‐Cl
提出了一种在回流条件下使用铜(II)促进肼基酞嗪环化脱氢反应合成Cu(II)-三唑并酞嗪配合物的新途径。将两个酞菁环化为相应的三唑酞菁配体,即3-吡啶-2--2-基-3,10b-二氢-[1,2,4]三唑并[3,4-a]酞嗪(TPP)和3-(3,10b二氢[1,2,4]三唑并[3,4-α]酞嗪-3-基) -苯甲酸(TP3COOH),随后在 原位络合铜(II),得到6新颖的Cu(II)-triazolophthalazine配合物取决于反应条件。讨论了Cu(II)-三唑酞嗪配合物的分子和超分子结构。金属部位在[Cu(TPP)Cl2 ] 2 ; 1和[Cu(TP3COOEt)Cl 2(H 2 O)] 2;4个双核络合物,在[Cu(TP3COOMe)2 Cl 2 ]中扭曲方形平面;3,[Cu(TP 3 COOH)2 Cl 2 ];5和[Cu(TP3COOH)2 Cl 2 ]·H 2 O; 图6是[Cu(TPP)(H
