Manganese Azides Based on Co‐Ligands with a Flexible Tail: Diverse Structural and Magnetic Properties

Abstract

, have been synthesized with Schiff-base co-ligands with flexible tails, and their structures and magnetic properties characterized. Complex 1 is composed of one-dimensional, uniform chains with double end-on (EO) azido bridges, complex 2 consists of (6,3) net layers in which double

A new two-dimensional manganese(II) coordination polymer with alternating double end-on and single end-to-end azido bridges: Crystal structure and magnetic properties

“…3. However, it should be noted that the fitted values for J and zJ 0 are only qualitatively valid for comparing with the results reported previously [32][33][34], so their comparability in magnitude does not meet the requirement of the molecular field approximation that zJ 0 should be much smaller than J [39]. These values are similar to those of related compounds, and confirm that the single EE and the double EO bridges mediate the antiferro-and ferromagnetic coupling between Mn(II) ions, respectively [32][33][34].…”

“…The shorter distance may be ascribed to the complementary interdigitation between the neighboring layers [32,33].…”

“…[32][33][34], the least-squares fit of the experimental data to the above expressions led to J = À5.31(3) cm À1 and zJ 0 = 4.5(2) cm À1 with g = 2.003 (2). experimental data is depicted in Fig.…”

“…There have been many reports on multidimensional manganese(II)-azido complexes in literature [26][27][28][29][30][31]. However, to the best of our knowledge, there are few examples of them containing alternating double EO and single EE azido-bridging modes with bidentate ligand [32][33][34]. Herein, we report the synthesis, structure and magnetic property of a novel two-dimensional manganese(II)-azido complex, [MnL(N 3 ) 2 ] n (1), where L is bidentate ligand (E)-3-(dimethylamino)-1-(pyridin-2-yl)prop-2-en-1-one.…”

“…In order to evaluate the magnetic interactions in 1, we employed an approximate approach that has been used for similar studies [32][33][34]. This method can give an exact coupling mode between magnetic centers although it is very tedious.…”
