Abstract

The crystal structure of the title complex features O—H⋯O hydrogen bonds, which form

(8),

(16),

(20) and

(22) ring motifs.

The title complex, [Cu(C₈H₁₈NO₅)Cl] or [Cu(H₄bis-tris)Cl], was obtained starting from the previously reported [Cu(H₅bis-tris)Cl]Cl compound. The deprotonation of the aminopolyol ligand H₅bis-tris {[bis(2-hydroxyethyl)amino]tris(hydroxymethyl)methane, C₈H₁₉NO₅} promotes the formation of a very strong O—H⋯O intermolecular hydrogen bond, characterized by an H⋯O separation of 1.553 (19) Å and an O—H⋯O angle of 178 (4)°. The remaining hydroxy groups are also engaged in hydrogen bonds, forming R ₂ ²(8), R ₄ ⁴(16), R ₄ ⁴(20) and R ₄ ⁴(22) ring motifs, which stabilize the triperiodic supramolecular network.

氯化(2-{(2-羟乙基)[三(羟甲基)甲基]氨基}乙醇拉托-κ5 N,O,O′,O′′,O′′)铜(II)

标题复合物[Cu(C8H18NO5)Cl]或[Cu(H4bis-tris)Cl]是从之前报道的[Cu(H5bis-tris)Cl]Cl化合物开始获得的。氨基醇配体 H5 双-三{[双（2-羟乙基）氨基]三（羟甲基）甲烷，C8H19NO5}的去质子化促进了非常强的 O-H...O 分子间氢键的形成，其特征是 H...O 间距为 1.553 (19) Å，O-H...O 角度为 178 (4)°。其余的羟基也以氢键结合，形成 R 2 2(8)、R 4 4(16)、R 4 4(20)和 R 4 4(22)环状结构，从而稳定了三周期超分子网络。
