Thiocyanate-bridged transition-metal polymers. 4. A study of the structural, electronic, and magnetic properties of some mono(2,2'-bipyridyl) transition-metal thiocyanates: zigzag polymeric chains based on Mn(bpy)(NCS)2 and Co(bpy)(NCS)2

Cu(I/II) Redox Control of Molecular Conformation and Shape in Chiral Tripodal Ligands: Binary Exciton-Coupled Circular Dichroic States

“…A similar problem with overlapping bands was observed in IR spectra of the complex Cu II (quinoline) 2 (NCS) 2 . The lack of apparent C−S stretching vibrations also excludes bridged structures (M−SCN−M) which should give multiplets in this region. , …”

Synthesis and Structural Characterization of [Mn(ethyl isonicotinate)2(N3)2]n, a Two-Dimensional Alternating Ferromagnetic−Antiferromagnetic Compound. Magnetostructural Correlations for the End-to-End Pseudohalide−Manganese System

“…The J values obtained for the end-to-end azido bridges are the first reported for the Mn(II)−azido system, and no comparison can be made at present to check our proposal, but in the literature there are reports of some d 5 or d 4 azido or thiocyanate bridged compounds, such as the chromium(II) dimer (NBu 4 ) 4 [Cr(NCS) 4 ] 2 ( J = −8.8 cm -1 ), the manganese(III) chains [Mn(acac) 2 (N 3 )] n or [Mn(acac) 2 (NCS)] n ( J = −5.3 and −1.5 cm -1 , respectively), the manganese(II) dimer [Mn 2 (tren) 2 (NCS) 2 ](BPh 4 ) 2 ( J = −0.2 cm -1 ), the two-dimensional [Mn(EtOH) 2 (SCN) 2 ] n complex, structurally analogous to 1 ( J = −0.6 cm -1 ), the manganese(II) chain [Mn(bipy)(NCS) 2 )] n ( J = −2.5 cm -1 ), or the manganese(III) [Mn(salen)(N 3 )] n and [Mn(salen)(NCS)] n chains ( J = −5.4 and −0.44 cm -1 , respectively), which, in agreement with the above conclusions, effectively show antiferromagnetic coupling in all cases.…”

Framework-structured weak ferromagnets

“…For Mn(II) and Co(II) compounds, the existing results are quite rare. 91,92 We investigated the 1D chain structure of [Co(SCN) 2 (bim)] (bim = 1,2-bis(imidazol-1-yl)ethane) and the 2D (4,4) layer of [Co(SCN) 2 (bte)] (bte = 1,2-bis(1,2,4triazol-1-yl)ethane). 93 The SCN À anions both act as double EE bridges.…”
