Copper salicylate describes a range of compounds containing copper(II) and salicylate. Many compounds are known. A simple species is:

Contents

[Cu(C6H4(OH)COO)2(H2O)2]·H2O. [2] [3]

Many adducts of copper(II) salicylates are known with amines and N-heterocyclic ligands.

Complexes

With other organic compounds

Crystallization with dimethylacetamide (DMAA) produces various complexes such as:

[Cu2(C6H4(OH)COO)4(H2O)]·2DMAA [4]

This complex has a lantern structure.

Heterometallic Complexes

Heterometallic complexes with various metals and solvents also exist, such as (with DMAA) the copper-strontium complex, [CuSr(C6H4(OH)COO)4(DMAA)4(H2O)], and the copper-barium complex, [CuBa(C6H4(OH)COO)4(DMAA)4(H2O)]. Both these and the related Cu2 complex took an excessively long time to crystallize, especially the copper-strontium complex which required an entire month. They share the lantern structure of the Cu2 complex. [4]
