Muconato‐bridged Manganese Coordination Polymer exhibiting rare Distorted‐trigonal Prismatic Coordination Arrangement

Abstract

Abstract. Novel poly[Mn(H 2 O)(dmb)(muco)] (1) (H 2 muco = trans,trans-muconic acid; dmb = 5,5Ј-dimethyl-2,2Ј-bipyridine) was obtained by self-assembly, one-pot, solution reaction. 1 crystallizes in a monoclinic system with P2 1 space group and forms an infinite onedimensional (1D) polymer. Remarkably, the six-coordinate Mn II display a rare distorted trigonal prismatic configuration. This unusual co-

Influence of the ancillary ligand on the crystalline structures and magnetic properties of mesaconato‐bridged Mn coordination polymers

“…This supramolecular array is, mainly, generated by the intermolecular interactions O(5)‐H(5B)⋅⋅⋅O(2), O(6)‐H(6 A)⋅⋅⋅O(3) and O(6)‐H(6B)⋅⋅⋅O(4) (Figure S1). Hence, polymer 1 is another example where the preference of distorted trigonal‐prismatic over the characteristic octahedral, or distorted octahedral, coordination geometry might be influenced by supramolecular interactions, as we detailed in a paper published previously [17] …”

“…Hence, polymer 1 is another example where the preference of distorted trigonal-prismatic over the characteristic octahedral, or distorted octahedral, coordination geometry might be influenced by supramolecular interactions, as we detailed in a paper published previously. [17] Polymer 2 crystallizes in an orthorhombic system with a P2 1 2 1 2 space group generating a 2D coordination array (Figure 2). The metal centers in 2 have a distorted octahedral geometry; the N2O4 hexa-coordinated sphere is composed of three mes ligands and one bpy ligand (Figure 2).…”

Synthesis, Structure, and Properties of a Dinuclear Cu(II) Coordination Polymer Based on Quinoxaline and 3,3-Thiodipropionic Acid Ligands

“…The two Cu(II) ions bonded to each other with a bond length of Cu atoms. One of the TDPH ligands was observed to bridge the two copper ions via the O1A and O2A of the C9A of the carboxylate group with bond lengths of 1.965 and 1.945 Å favourably comparing with the bond length range of 1.911 -1.998 Å observed for Cu----O bonds in similar compounds 8,22,[24][25][26][27][28]. The quinoxaline molecules coordinated to the Cu(II) ions through the N1C and N2C atoms in a monodentate manner (Cu1-N1C = 2.287 Å, Cu2-N2C = 2.263 Å) with bond lengths within the range of 1.98-2.328 Å reported in literature for N-Cu(II) interactions in similar compounds having the Cu-N bonds 27,28.…”
