(2,9-Dimethyl-1,10-phenanthroline)(4-hydroxypyridine-2,6-dicarboxylato)copper(II) trihydrate

Abstract

In the title complex, [Cu(C7H3NO5)(C14H12N2)]·3H2O, there are two independent neutral mol­ecules of the Cu complex along with six mol­ecules of water of hydration in the asymmetric unit. The CuII atoms in each complex adopt a distorted square-pyramidal coordination geometry being penta­coordinated by one N and two O atoms of 4-hydroxy­pyridine-2,6-dicarboxyl­ate anions and two N atoms of 2,9-dimethyl-1,10-phenanthroline (dmp) molecules. In the crystal structure, there are O—H⋯O and C—H⋯O hydrogen bonds and five π–π stacking inter­actions with centroid–centroid distances in the range 3.620 (1)–3.712 (1) Å. In addition, a C—H⋯π inter­action between a heterocyclic ring of dmp is observed to reinforce the crystal cohesion.

A brief review on formation of (H2O)n clusters in supramolecular proton transfer compounds and their complexes

“…26c). The water molecular cluster with n = 4 in the crystal structure of [Cu(hypydc)(phen)].3H 2 O [31] forms the triangle shape with three water molecules in which the last water molecule is in the center of a base chain (Fig. 27) (pydc)(pydcH)(H 2 O) 2 ].4H 2 O} n compounds [12] found in the form of a simple chain (Fig.…”

Synthesis, Crystal Structure, Spectroscopic, Electrochemical and Antimicrobial Properties of Cu(II) Complex with the Mixed Ligands of 2,9‐Dimethyl‐1,10‐phenanthroline and 4‐Hydroxypyridine‐2,6‐dicarboxylic Acid

“…Two complexes of Cu(II) with chelidamic acid, 1,10-phenanthroline and neocuproine were synthesized. 37,38 The title complex is different from another one that has been synthesized by chelidamic acid and neocuproine in crystal system, space group, cell parameters and uncoordinated water molecules, however in both complexes one chelidamate and one neocuproine have coordinated to Cu(II) atom. The Cu(II) atoms in complex adopt a distorted square-pyramidal coordination geometry being pentacoordinated by one N and two O atoms of 4-hydroxypyridine-2,6-dicarboxylate anion and two N atoms of 2,9-dimethyl-1,10-phenanthroline (dmp) molecule.…”

Syntheses, crystal structures, and optical properties of a series of transition metal coordination polymers with chelidamic acid and 4,4′-bipyridine

“…A large number of complexes containing chelidamic acid have been reported, and they play a significant role in designing molecules and preparation of functional materials [3][4][5][6][7][8]. There are relatively fewer complexes built by chelidamic acid and bridging ligands such as 4,4 0 -bipyridine are chosen for demonstrated ability to act as rods linking metal centers to give extended solids with diverse topologies [9].…”
