Abstract
[Co2(L)Ce(OAc)3(CH3CH2OH)]·1.5CH3OH∙0.5CH2Cl2, a heterotrinuclear Co(II)-Ce(III) bis(salamo)-type complex with a symmetric bi(salamo)-type ligand H4L and an acyclic naphthalenediol moiety, was designed, synthesized and characterized by elemental analyses, FT-IR, UV-Vis and fluorescence spectroscopy and X-ray crystallography. The X-ray crystallographic investigation revealed the heterotrinuclear complex consisted of two Co(II) atoms, one Ce(III) atom, one (L)4‒ unit, three μ2-acetate ions, one coordinated ethanol molecule, one and half crystallization methanol molecule and half crystallization dichloromethane molecule. Two Co(II) atoms located in the N2O2 coordination spheres, are both hexacoordinated, with slightly distorted octahedral geometries. The Ce(III) atom is nine-coordinated and located in the O6 cavity possesses a single square antiprismatic geometry. In addition, supramolecular interactions exist in the Co(II)-Ce(III) complex. Two infinite 2D supramolecular structures are built via intermolecular O–H···O, C–H···O and C–H···π interactions, respectively.
Highlights
Salen (N,N-disalicylideneethylenediamine) is a versatile important compound that has been widely used in coordination chemistry and organometallic chemistry [1–8]
Our research group is focused on the synthesis and study of 3d–4f heterometallic salamo-type complexes [14,16,49]
The synthesis of the bi(salamo)-type ligand H4 L is shown in Scheme 1. 2,3-Dihydroxynaphthalene1,4-dicarbaldehyde was prepared according to a literature procedure [77]. 2,3-Dihydroxynaphthalene-1,4dicarbaldehyde and 2-[O-(1-ethyloxyamide)]oxime-6-methoxy- phenol were synthesized according to an analogous method [78,79]
Summary
Salen (N,N-disalicylideneethylenediamine) is a versatile important compound that has been widely used in coordination chemistry and organometallic chemistry [1–8]. Salen-type compounds are tetradentate ligands with a N2 O2 coordination environment that can usually coordinate with transition metal ions to afford diverse metal complexes. A number of salen-type metal complexes have already been synthesized to study their structures and applied in various fields for their magnetic properties [9–14], catalytic action [15,16], electrochemistry [17,18], in biological systems [19–28], supramolecular architectures [29–37], their luminescent properties [38–44], and in optical sensors [45] and nonlinear optical materials [46]. Our research group is focused on the synthesis and study of 3d–4f heterometallic salamo-type complexes [14,16,49]. Based on these points of view, we have designed and synthesized a symmetric bi(salamo)-type ligand H4 L and its corresponding heterotrinuclear Co(II)-Ce(III) 3d–4f complex. The structure and fluorescence properties of the Co(II)-Ce(III) complex were studied
