Poly[diaqua[μ-1,4-bis(imidazol-1-ylmethyl)benzene-κ²N³:N^3′](μ-trans-cyclohexane-1,4-carboxylato-κ²O¹:O⁴)manganese(II)]: a three-dimensional hydrogen-bonding α-polonium net

Abstract

In the title coordination compound, [Mn(C8H10O4)(C14H14N4)(H2O)2]n, each Mn(II) centre occupies an inversion centre. The 1,4-bis(imidazol-1-ylmethyl)benzene (1,4-bix) ligand and the trans-cyclohexane-1,4-dicarboxylate dianion (chdc) both function in bridging modes, linking adjacent Mn(II) centres into a two-dimensional four-connected (4,4) network. These two-dimensional layers are stacked in a parallel mode. Hydrogen bonds between water molecules and carboxylate O atoms link neighbouring (4,4) networks, yielding a three-dimensional alpha-polonium net.
