“…The emission of the compound is tentatively due to intraligand fluorescence emission because of the energy gap between the π→π * molecular orbits of the free ligand [25], but slightly modified by metal coordination. Similar fluorescence phenomenon of MOFs based on Ni 2+ has been reported previously [34,35].…”

A novel 3D metal-organic framework (MOF) with remarkable thermal stability, Ni(BIC) 2 ·2.5H 2 O (JUC-86) (HBIC = 1-H-benzimidazole-5-carboxylic acid and JUC = Jilin University China), has been synthesized under hydrothermal conditions. It crystallizes in tetragonal symmetry with P4 3 2 1 2 space group. The 3D structure consists of channels assembled from triple helices with a 4.5 × 4.5 Å 2 aperture, which are formed by the parallel alignment of three infinite helical chains. The thermogravimetric analysis (TGA) and powder X-ray diffractions (PXRD) indicate JUC-86 with high thermal stability (up to 350 °C). metal-organic framework, triple helices, thermal stability, fluorescence

“…The Mg atom occupies a special position on an inversion centre and has an octahedral coordination environment formed by six water molecules. This geometry has been observed often in other compounds containing an Mg centre (Feng et al, 2010;Yang, Chen et al, 2011;Yang, Feng et al, 2011). The O-Mg-O angles in 5-(pyridinium-3yl)tetrazol-1-ide hexaaquamagnesium dichloride (Dai & Chen, 2011) are in good agreement with those found in (II), whereas the Mg-O bond lengths range from 2.0526 (14) to 2.0965 (16) Å and from 2.0496 (13) to 2.1231 (16) Å for the two compounds, respectively.…”

Two alkaline earth-tetrazole compounds, namely catena-poly[[[triaquamagnesium(II)]-μ-5,5'-(azanediyl)ditetrazolato-κ(3)N(1),N(1'):N(5)] hemi{bis[μ-5,5'-(azanediyl)ditetrazolato-κ(3)N(1),N(1'):N(2)]bis[triaquamagnesium(II)]} monohydrate], {[Mg(C(2)HN(9))(H(2)O)(3)][Mg(2)(C(2)HN(9))(2)(H(2)O)(6)]0.5·H(2)O}n, (I), and bis[5-(pyrazin-2-yl)tetrazolate] hexaaquamagnesium(II), (C(5)H(3)N(6))[Mg(H(2)O)(6)], (II), have been prepared under hydrothermal conditions. Compound (I) is a mixed dimer-polymer based on magnesium ion centres and can be regarded as the first example of a magnesium-tetrazolate polymer in the crystalline form. The structure shows a complex three-dimensional hydrogen-bonded network that involves magnesium-tetrazolate dimers, solvent water molecules and one-dimensional magnesium-tetrazolate polymeric chains. The intrinsic cohesion in the polymer chains is ensured by N-H...N hydrogen bonds, which form R(2)(2)(7) rings, thus reinforcing the propagation of the polymer chain along the a axis. The crystal structure of magnesium tetrazole salt (II) reveals a mixed ribbon of hydrogen-bonded rings, of types R(2)(2)(7), R(2)(2)(9) and R(2)(4)(10), running along the c axis, which are linked by R(2)(4)(16) rings, generating a 4,8-c flu net.

Abstract. In whatever state of bonding -whether covalent to an organic residue or a heteroatom, or polar to ionic in contact with a metal -the azide moiety N 3 is characterized by its high potential of reactivity which essentially manifests itself in two basic processes: the elimination of dinitrogen and the entry into 1,3-dipolar cycloadditions with suitable dipolarophiles, the latter of which clearly predominates the chemistry of azide, also that of its metal compounds. In a preceding review entitled "Part I -Metal Azides: Overview, General Trends and Recent Developments" which was meant to lay the foundations for the present paper, these and other reactions have already been touched upon. The present review -Part II -now focusses in great detail on the formation of five-membered heterocyclestetrazol(at)es, triazol(at)es, triazolin(at)es, thiatriazol(at)es, etc. as well as various consecutive products -from azide and nitriles, isocyanides, alkynes, alkenes and heteroallenes (CS 2 , RN=C=S) in the ligand sphere of the metal. Generally, these [3+2]-cycloadditions are found to CONTENTS
