“…Coordination of the CN ligand to a second metal ion through its nitrogen atom results in a displacement to higher wavelengths. 66 32,63 The 1,3-diaminopropane ligand is also characterized by the presence in the IR spectrum of bands due to the ν(NH) stretching vibrations of the NH 2 groups, in the 3150-3350 cm -1 region, and to the ν(CH) stretching vibrations of the CH 2 groups, in the 2800-2980 cm -1 region. 68 Immersion Calorimetry and Heat of Structural Transformation.…”

“…The hexacyanometalates, M II (CN) 6 4-and M III (CN) 6 3-, are good building blocks, and a number of multidimensional systems have been synthesized, some with interesting magnetic properties. [29][30][31][32][33][34] Interest in the gas sorption properties of these compounds has increased in recent years. 35 However, only a small number of coordination polymers based on hexacyanometalates have been reported as being porous.…”

Three new bimetallic framework compounds, namely, (([Cd 3 (tn) ). They have been characterized by IR, X-ray diffraction, elemental analysis and immersion calorimetry. All three compounds have three-dimensional structures, with both the organic ligand and the cyanide groups acting as bridges. Compounds 1 and 3 have channels occupied by water molecules of crystallization. All three complexes are stable indefinitely when exposed to the air at room temperature; however, when compounds 1 and 3 are heated, they lose the water molecules of crystallization. The powder X-ray diffractograms of these dried and as yet unknown species are different from those of the original compounds. However, in a humid atmosphere both dried compounds readsorb water molecules and revert to the original structures, as shown by powder X-ray diffraction measurements. The adsorption properties of compounds 1 and 3 were studied using immersion calorimetry and in situ powder X-ray diffraction. In the case of compound 3 the heat of the structural transformation on rehydration was found to be ca. 19 ( 3 J/g.

“…(MacGillivray & Lukehart, 2014;Kaskel, 2016). Nickel(II) complexes of the 14-membered macrocyclic tetraamine ligands, in particular of cyclam and its C-alkylated derivatives (cyclam = 1,4,8,11-tetraazacyclotetradecane, C 10 H 24 N 4 ), are widely used as metal-containing building units for the construction of MOFs (Lampeka & Tsymbal, 2004;Suh & Moon, 2007;Suh et al, 2012;Stackhouse & Ma, 2018;Lee & Moon, 2018) (Escuer et al, 1993), cyanide (Koo et al, 2003), and cyanometalate (Koo et al, 2003;Shek et al, 2005;Talukder et al, 2012;Ni et al, 2014) bridging anions have been characterized by single-crystal X-ray diffraction.…”

The asymmetric unit of the title compound, trans-diaqua(1,4,8,11-tetraazaundecane-κ4 N 1,N 4,N 8,N 11)nickel(II) bis(pyridine-2,6-dicarboxylato-κ3 O 2,N,O 6)nickel(II) {[Ni(L)(H2O)2][Ni(pdc)2] where L = 1,4,8,11-tetraazaundecane (C7H20N4) and pdc = the dianion of pyridine-2,6-dicarboxylic acid (C7H3NO4 2−)} consists of an [Ni(L)(H2O)2]2+ complex cation and a [Ni(pdc)2]2– anion. The metal ion in the cation is coordinated by the four N atoms of the tetraamine ligand and the mutually trans O atoms of the water molecules in a tetragonally elongated octahedral geometry with the average equatorial Ni—N bond length slightly shorter than the average axial Ni—O bond [2.087 (4) versus 2.128 (4) Å]. The ligand L adopts its energetically favored conformation with five-membered and six-membered chelate rings in gauche and chair conformations, respectively. In the complex anion, the NiII ion is coordinated by the two tridentate pdc2– ligands via their carboxylate and nitrogen atom donors in a distorted octahedral trans-NiO4N2 geometry with nearly orthogonal orientation of the planes defining the carboxylate rings and the average Ni—N bond length [1.965 (4) Å] shorter than the average Ni—O bond distance [2.113 (7) Å]. In the crystal, the NH donor groups of the tetraamine, the carboxylic groups of the pdc2– anion and the coordinated water molecules are involved in numerous N—H...O and O—H...O hydrogen bonds, leading to electroneutral sheets oriented parallel to the (001) plane.

“…48 At the same time only a few examples of coordination polymers containing [Ru(CN) 6 ] 4-have been reported. [49][50][51][52] On the other hand, chiral structures are a new target for such lattice architectures, chirality being an essential factor for inducing specific physical properties, for example, second harmonic generation (SHG), magnetochiral dichroism (MChD), ferroelectricity, etc. [53][54][55][56] A chiral network would allow selective binding of chiral guests, and the presence of different types of metal ions could enable specific tuning of the electronic properties.…”

ABSTRACT:The syntheses, crystal structures, and adsorption/desorption properties of two novel chiral three-dimensional cyanobridged bimetallic assemblies, { [Cu(1R,2Rchxn) (11) , and Z ) 1. Compounds 1 and 2 can be described as nanoporous cyano-bridged frameworks, in which alternating trans- 6 diamondoid frameworks. In both structures there are large cavities filled with H 2 O molecules which show guestdependent dynamic behavior. The chemical rearrangement of the framework is driven by the loss or addition of water molecules, as proved unequivocally by single-crystal and powder X-ray diffraction analyses. These changes are also fully reversible. The two types of frameworks reported show different behavior upon drying, falling within the category of "recoverable collapsing" and "guest-induced re-formation" framework materials.
