TLDR
A series of Ni(II)-and Cu(II) complexes of the hexaaza macrocycles, 3,6,9,17,20,23,23-hexaazatricyclo[23.3.1.2.1 11,15 ]triaconta-1(29),11,30,12,14,25,27-,27-,24,27,hexaene (L 2 ), have been prepared and the crystal structures determined for [Ni 2 L 1 (O 2 CCH 3 ) 2 (HAbout:

The development of compartmental macrocyclic Schiff bases and related polyamine derivatives
TL;DR: In this paper, the role of compartmental ligands, i.e. their ability to bind two or more metal ions in close proximity into two identical or different compartments, and their relevance in modulating the type and the extent of mutual interaction between the metal ions inside the adjacent chambers are reviewed.

TL;DR: The synthesis and characterisation of the new macrocyclic ligand 6-methyl-2,6, 10-triaza-[11]-12,25-phenathrolinophane (L1), which contains a triamine aliphatic chain linking the 2,9 positions of 1,10-phenanthroline and of its derivative L2, composed by two L1 moieties connected by an ethylenic bridge, are reported.

TL;DR: A potentiometric and NMR study in aqueous solution reveals that H2L is in a zwitterionic form, and protonation of the cresolate oxygens occurs only with the formation of the highly charged (H5L)(3+) and (H6L)(4+) species at acidic pH values.

TL;DR: The selectivity of a dinuclear copper(II) macrocycle (Cu2L) in an eosin Y displacement assay is reassessed and it is concluded that Cu2L is not suitable for oxalate sensing in a biological matrix unless interfering compounds are selectively removed or masked.

Carbon dioxide fixation by zinc(II) complexes with macrocyclic ligand
Zhao-Peng Qi,Shu-An Li,Yong-Qing Huang,Guan-Cheng Xu,Guang-Xiang Liu,Ling-Yan Kong,Wei-Yin Sun +6 more
TL;DR: In this article, the authors showed that carbon dioxide from air was absorbed and converted to carbonate anion in the formation of two zinc(II) coordination complexes and showed that the dinuclear units of [Zn 2 (L)] 4+ in both complexes are linked together by carbonates anions to form 1D infinite chain structure.

New hexaaza macrocyclic binucleating ligands. Oxygen insertion with a dicopper(I) Schiff base macrocyclic complex
TL;DR: In this paper, the crystal structure of an isomeric form of the Schiff base was reported, and the amber binuclear Cu(I) complex of the tetraaza macrocyclic Schiff base combines with a molar equivalent of dioxygen to form a green binuclear CU(II) complex, wich contains a bridging hydroxide ion and, by oxygen insertion, an bridging phenolate donor.

Macrocyclic complexes as models for nonporphine metalloproteins
TL;DR: This chapter discusses on the metalloprotein active sites and those for which the role of the metal ion is largely structural are neglected, and the problems of modeling these sites are different, in kind as well as in degree, from those of modeling nonporphine sites.
