Enantiopure heterobimetallic single-chain magnets from the chiral Ru^IIIbuilding block

Abstract

A pair of one-dimensional enantiomers based on the versatile chiral dicyanoruthenate(III) building block have been synthesized and they are chiral single-chain magnets with the effective spin-reversal barrier of 28.2 K.

Influence of metal coordination and co-ligands on the magnetic properties of 1D Co(NCS)2 coordination polymers

“…[14][15][16][17][18][19][20][21] This might be one of the reasons why an increasing number of such compounds were recently reported and some selected examples are given in the reference list. [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] For the synthesis of such compounds cations of large magnetic anisotropy must be connected by ligands into 1D magnetic chains with a high ratio between intra-and interchain interactions. Therefore, for optimization of the properties of such materials systematic investigations of the influence of chemical and structural modification on their magnetic properties might be helpful.…”

Synthesis, crystal structure, and magnetic characterization of chiral Schiff-base manganese(III) complex containing cocrystallized crown ether molecule

“…According to the earlier reports [13][14][15][16] the Schiff-base Mn(III) compounds based on chiral cyclohexanediamine were good candidates for assembling chiral cyanide-bridged magnetic complexes. Synthetic approach to the new chiral cyanide-bridged complex was based on the reaction of 8 ], which contained the maximum number of the cyanide groups in the polycyanometallate family.…”

Three Chiral Cyanide-Bridged Cr–Cu Complexes: Synthesis, Crystal Structures and Magnetic Properties

“…It is known that the chirality can be reasonably introduced into the cyanide bridging system by coordinating the paramagnetic metal ions (Ni 2+ , Cu 2+ , Mn 2+/3+ , etc) with a chiral auxiliary ligand (chiral amine, chiral Schiff base, etc.). [39][40][41][42][43][44][45][46] In order to find new chiral molecular magnetic complexes and further enrich the low-dimensional cyanide bridged trans-dicyano-based compounds, we investigated the reactions of trans-dicyanidochromium(III) precursors with chiral organic amine copper compounds (Scheme 1) and obtained three new cyanide-bridged chiral Cr(III)-Cu(II) complexes, including the two enantiomeric complexes…”
