Source of materials

A mixture of Mn(CH3COO)2⋅4H2O (0.5 mmol), phthalic acid (0.5 mmol), 1-(imidazo-1-ly)-4-(1,2,4-triazol-1-ylmethyl)benzene (itmb) (0.50 mmol) and distilled water (25 mL) was heated in a 50 mL stainless steel reactor with a Teflon liner 373 K for 8 h, followed by slow cooling to room temperature until colourless crystals of the title compound formed.

Experimental details

All H atoms were positioned geometrically (O—H = 0.85 Å and C—H = 0.95 Å) and refined using a riding model, with Uiso(H) = 1.2Ueq(C), Uiso(H) = 1.5Ueq(O).

Discussion

The design and construction of metal-organic frameworks (MOFs) with well-regulated network structures has been provoked significant interest on these functional materials [4], [5], [6], [7]. The organic ligands, which have their differences in the size, the flexibility, the coordination ability, the number of the carboxylate groups, the positions of the carboxylate groups and so on, are important in the design of frameworks [8], [9], [10]. In addition, containing triazol ligands [11], [12] are known to be connectors of coordination networks.

In this paper, we select phthalic acid to react with Mn(II) ions and 1-(imidazo-1-ly)-4-(1,2,4-triazol-1-ylmethyl)benzene (itmb) to obtain a new coordination polymer. The asymmetric unit of the title structure consists of one half Mn2+ ion, one 1-(imidazo-1-ly)-4-(1,2,4-triazol-1-ylmethyl)benzene (itmb), two water molecules and one phthalate monoanion. Each Mn(II) atom is coordinated by two triazolyl nitrogen atoms and two imidazolyl nitrogen atoms from four different itmb ligands and two oxygen atoms from two water molecule to furnish a [MnN4O2] six-coordinate distorted octahedral geometry (cf. the figure). The Mn—O bond lengths are 2.1678(19) Å, and the Mn—N distances are 2.2634(18) and 2.269(2) Å, both of which are in the normal range. The bond angles around the Mn(II) are in the ranges of 87.84(6)–180°. Moreover, the coordinated water molecules and the solvated water molecules, the solvated water molecules and carboxyl O atoms, the coordination water molecules and carboxyl O atoms show hydrogen bonding interactions with d(O—H⋯O) = 2.625(2)–2.7460 Å. Through hydrogen bonds coordination polymers and water molecules are interlinked to form the 3D network.
