“…In this work, a series of cationic complexes of Co 2+ and Zn 2+ was synthesized with tunable molar ratio of TEA/M 2+ , in which triethanolammonium salts consisted of M(TEA) 2+ or [M(TEA 2 )] 2+ . [ 29 ] Along with the increasing of TEA, the heterometallic complexes were more prone to be [M(TEA 2 )] 2+ with four O atoms lying in the equatorial plane and two N atoms in the axial position (CoN 2 O 4 ), while two hydroxyethyl moiety branches extend outside. Subsequently, as is verified by the X‐ray diffraction (XRD) patterns in Figure S1, Supporting Information, the later added Lewis base (mim − ) with stronger coordination ability broke the hydrogen bonds and reconstructed with Zn 2+ /Co 2+ into Zn/Co‐ZIF‐L (MN 4 ).…”

Rational manipulation of multimetal hybrid materials (HMs) with tunable substitution or phases is evolving as an effective strategy to meet the controllable electromagnetic (EM) properties and EM wave (EMW) absorption. Herein, a new thermodynamic and kinetic cocontrol strategy is proposed to construct Zn/Co bimetal HMs with tuning ion and phase hybridization for synergistic effect on EM properties for the first time. Auxiliary chelating agent triethanolamine (TEA) dominates the phase separation by stepwise Zn/Co deposition in metal-organic frameworks, then the pyrolysis process under gradient temperature give rise to controllable ion hybridization products due to thermal motion. Benefiting from the tunable collaboration between defects polarization and interfacial polarization, the 700 °C HMs exhibit ultrahigh EM parameters and EMW absorption, of which products with no TEA deliver the effective absorbing bandwidth of 4.80 GHz (1.6 mm) and minimum reflection loss of −45.85 dB. The results indicated that synergistic effect of ion and phase hybridization can improve the defects induced "polarization centers" and coherent interfaces induced interfacial polarization. Furthermore, the comprehensive research and deep understanding on respective contribution of hybridization forms provide a precise inspiration in developing bimetal and even multimetal ferrite with tunable hybridization structure.

“…All bonding distances surrounding Zn centers are comparable with the corresponding values found in other Zn II complexes. [38] The angles between two poles and Zn1/Zn4 centers are far from 180°, indicating a significantly distorted trigonal-bipyramidal environment. The distortion of the tetrahedral coordination geometry around the Zn2 and Zn3 centers are manifested by the OÀ ZnÀ O angles, which lie in the range 93.71(15)-124.04(14)°.…”

Two new MOFs with a Zn 4 SBU, namely {[Zn 2 (teaH)] • 2(μbdc) 0.5 } 2 (I) and {[Zn 2 (MedeaH)] • 3(μ-bdc) 0.5 } 2 • (H 2 O) (II), have been prepared through altering polyalcohol amines. Singlecrystal X-ray analysis reveals that their topological controllability mainly arise from the SBU connection being dependent on ethanolic arms of polyalcohol amines. Topological evolution is used to improve our understanding for the feasibility to tune their topology toward SBU connection. Compound I shows a 4 4 network in which the Zn 4 rings act as planar four-connected node, whereas II features a 3D pcu network based on the nonplanar six-connected Zn 4 SUBs. The luminescent properties of the two compounds have also been investigated.

“…Recently, it has been reported that Cu(II) complexes of TEA with salts of salicylic, cinnamic, and succinic acids, 6 Zn(II) and Cu(II) cinnamate with TEA complexes 61 showed antimicrobial activity against bacteria E. coli, S. aureus, M. smegmatis, fungi C. albicans and A. niger. In addition, it has been shown that TEA with Cu(II) picrate and Ag(I) complexes appeared to exhibit mild to moderate activity towards S. marcescens, S. japonicum, S. maltophilia and S. aureus.…”

A mixed ligand Cd(II) complex [Cd(IsoPht)(TEA)H2O]·3H2O was synthesized for the first time by using isophthalic acid (H2IsoPht) and tetradentate triethanolamine (TEA) and characterized by X-ray single-crystal diffraction, FT-IR, and thermogravimetric analysis (TGA). This novel complex crystallizes in the triclinic system with P-1 space group and distorted monocapped trigonal prismatic geometry. The Cd(II) has seven coordinates with bidentate IsoPht, a TEA in the tetradentate mode, and an aqua ligand. The fluorescence properties of the Cd(II) complex and TEA ligand were investigated at room temperature. The present Cd(II) complex was also tested for its antimicrobial activity by in vitro agar diffusion method against some Gram-positive and Gram-negative bacteria and a fungus.
