From zero- to three-dimensional heterobimetallic coordination polymers with the [Pt{SSC-N(CH₂COO)₂}₂]⁴⁻ metalloligand

Abstract

Heterobimetallic compounds of the type M’2[Pt(L)2] (L = N-dithioato-iminodiacetate, {SSC-N(CH2COO)2}3–) containing different bivalent, oxophilic metals M’ were prepared in a straightforward manner from [Pt(H2L)2] and the respective metal acetates, M’(OAc)2...

Alkali Metal Dithiocarbamato Carboxylates (DTCCs) – Synthesis, Properties, and Crystal Structures

“…[4,22] The efficient isolation of the solid products from their aqueous solutions is particularly demonstrated with 1-Na, which has been isolated as a liquid trihydrate 1-Na ⋅ 3H 2 O without acetone extraction by Frank, [16] and was now observed as a solid monohydrate 1-Na ⋅ H 2 O. On the other hand, a series of N-dithioato-l-prolinates (6) has been previously reported by Tlahuext et al and characterized as the anhydrous salts. [18] This report seems questionable in the light of our results, as we identified the respective compounds as the hydrates 6-Li ⋅ 4H 2 O, 6-Na ⋅ H 2 O, and 6-K ⋅ 3H 2 O.…”

“…Dithiocarbamate-substitued carboxylates (DTCCs) are relevant in different fields of research, including biomedical chemistry [1][2][3] and material sciences. [4][5][6] Moreover, DTCC salts can be used as flotation agents for ore mining. [7] In transition metal complexes, the dithiocarbamate group is usually coordinated to a late transition metal in a kS,kS'-chelating mode, forming stable square-planar (Ni, Pd, Pt, Cu(II), Au(III)), octahedral (Co-Ir), or polynuclear (Cu(I), Ag(I), Au(I)) complexes.…”

[8] The carboxylate groups are attached to an oxophilic transition or main group metal ion, [4][5][6]9] protonated, [4,[10][11][12] or esterified. [1,2] Additionally, main group metal DTCCs are known, e. g. derivatives of β-, γ-, and δ-amino acids with tetravalent tin, in which both the O and S donor groups are metalcoordinated.…”

Structural evolution from preorganized mononuclear triazamacrocyclic metalloligands to polynuclear metallocages and heterometallic 2D layers: modular architectures, assembly tracking and magnetic properties

“…[27][28][29][30] Studies have also found that the construction of homo-or hetero-metallic architectures using metalloligands is controlled by several reaction factors, such as the pH of the medium, the size of the second metal ion, metalloligand size and geometry, the ratio of the metalloligand to the second metal ion, and the type of counter anion. [31][32][33][34][35][36] These factors may determine the nuclearity, topological structures, and the physical/chemical properties of the constructed assemblies. However, more investigation is needed to elucidate the influence of reaction parameters on the assembly behaviors of different metalloligands for the directed synthesis of the desired coordination architectures.…”

The Flexible On-Surface Self-Assembly of a Low-Symmetry Mabiq Ligand: An Unconventional Metal-Assisted Phase Transformation on Ag(111)

“…The surface-directed synthesis and self-assembly of bi- and multi-metallic coordination networks and complexes are crucial steps to increase the complexity of heterogeneous systems, prompt advances in surface functionalization, and enhance our fundamental understanding of their properties. Multinuclear compounds can also promote cooperative multi-electron processes , and enable new reaction pathways through synergistic effects. − With this in mind, we have now examined the surface immobilization of the unique macrocyclic Mabiq molecule (Figure ). Mabiq resembles some of the aforementioned tetrapyrrole systems; however, as it comprises a diketiminate unit connected to an aromatic biquinazoline group with a bipyrimidine core, it provides two distinct metal coordination sites.…”
