Interpenetrating 2D Manganese(II) Coordination Polymer Supported by 4,4′‐Bis(dimethoxyphosphorylmethyl)‐biphenyl Ligands

Abstract

A novel coordination polymer [Mn(bdpbp) 2 (NO 3 ) 2 ] n (1), where bdpbp ＝ 4,4'-bis(dimethoxyphosphorylmethyl)biphenyl, was prepared under mild condition. The structure has been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, IR spectra, luminescent property and thermogravimetric analyses. Structure of 1 exhibits infinite grid frameworks and forms two fold interpenetrating nets. Weak C-H…O hydrogen bonds ensure the formation and stability of a three dimensional supramolecular network.

Anisotropic compressibility of the coordination polymer emim[Mn(btc)]

“…Thus, it is evident that as a consequence of the compression the Mn atom becomes seven-coordinated. This is reasonable as Mn II is known to form complexes with up to eight ligands (see, for example, Li et al, 2013;Lethbridge et al, 2003;Zhang et al, 2009). While the Mn-O bond lengths behave similarly to pressure and temperature as shown above, the changes to the coordination environment around Mn are significantly different.…”

Coordination Polymers based on the Neutral Ditopic Ligand (C6H4PO(OCH3)2)2 Involving some f‐Block Elements

“…This stimulated us to explore the solvent free microwave assisted synthesis of (C 6 H 4 PO(OMe) 2 ) 2 which has been mentioned in literature before however with very limited characterization . So far the ligand properties have been explored with cadmium and manganese as central metal atoms, affording a two‐dimensional coordination polymer. Herein we further report the use of this ligand for complexation with lanthanides and earth alkaline metals, as well as uranium.…”

Structural and Luminescence Properties of Anthracene- and Biphenyl-Based Lanthanide Bisphosphonate Ester Coordination Polymers

“…The Sm­(NO 3 ) 3 core shows no significant deviation in bond lengths compared to other samarium-based coordination polymers . As in polymer 1 , the PO bond and the angles around the phosphorus atom show no large deviation from standard values either for free phosphonates or for coordination polymers. ,,,, …”

“…23 As in polymer 1, the PO bond and the angles around the phosphorus atom show no large deviation from standard values either for free phosphonates or for coordination polymers. 19,20,22,23,36 The rest of the lanthanide metals (Eu, Gd, Tb, Dy, Tm, Yb, Lu) and yttrium form the type III polymer motif for which the europium polymer will be described as representative example. Again, the repeating unit (space group P2 1 /c) consists of one ligand coordinated to a Eu(NO 3 ) 3 core along with a molecule of methanol (Figure 4) adding up to a coordination number of 9 at the metal.…”
