Bis(?-2-carboxymethyl-2-hydroxy-butane-dioato)bis-[diaqua-manganese(II)]-1,2-bis-(pyridin-4-yl)ethane-water (1/1/2).

ABSTRACT: The asymmetric unit of the title compound, [Mn(2)(C(6)H(6)O(7))(2)(H(2)O)(4)]·C(12)H(12)N(2)·2H(2)O, comprises half of a centrosymmetric dimer, half of a 1,2-bis-(pyridin-4-yl)ethane and one water mol-ecule. Two citrate ligands bridge two Mn(II) ions, the Mn(II) ion being coordinated by four O atoms from the citrate(2-) ligands and two water O atoms, forming a distorted octa-hedral environment. In the crystal, O-H?O hydrogen bonds link the centrosymmetric dimers and lattice water mol-ecules into a three-dimensional structure which is further stabilized by inter-molecular ?-? inter-actions [centroid-centroid distance = 3.792?(2)?Å].

Bis(?-2-carb-oxy-methyl-2-hy-droxy-butane-dioato)bis-[diaqua-manganese(II)]-1,2-bis-(pyridin-4-yl)ethene-water (1/1/2).

Project description:The asymmetric unit of the title compound, [Mn2(C6H6O7)2(H2O)4]·C12H10N2·2H2O, contains half of the centrosymmetric Mn complex dimer, half of a 1,2-bis-(pyridin-4-yl)ethene mol-ecule, which lies across an inversion center, and one water mol-ecule. Two citrate ligands bridge two Mn(II) ions, and each Mn(II) atom is coordinated by four O atoms from the citrate ligands (one from hy-droxy and three from carboxyl-ate groups) and two water O atoms, forming a distorted octa-hedral environment. In the crystal, O-H?O and O-H?N hydrogen bonds link the centrosymmetric dimers and lattice water mol-ecules into a three-dimensional structure which is further stabilized by inter-molecular ?-? inter-actions [centroid-centroid distance = 3.959?(2)?Å]. Weak C-H?O hydrogen bonding interactions are also observed.

Project description:The reaction of manganese seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) leads to the title compound, {[Mn(NCSe)2(C12H12N2)(CH3OH)2]·C12H12N2} n . The Mn(II) cation is coordinated by two N-bonded seleno-cyanate anions, two bpa ligands and two O-bonded methanol mol-ecules, within a slightly distorted octa-hedral geometry. The Mn(II) cations and the non-coordinating N-donor ligands are located on centers of inversion while the coordinating N-donor co-ligands are located on a twofold rotation axis. In the crystal, the Mn(II) cations are linked into chains along the c-axis direction by the bpa ligands. The chains are further connected via a non-coordinating bpa ligand into layers parallel to (3-10) via O-H?N hydrogen-bonding inter-actions.

Project description:In the title compound, [Cd(2)(C(6)H(8)O(4))(2)(C(16)H(20)N(4))(H(2)O)(4)](n), penta-gonal-bipyramidally coordinated Cd(II) ions are connected into {Cd(2)(2,2-dimethyl-succinate)(2)(H(2)O)(4)} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands into [Cd(2)(2,2-dimethyl-succinate)(2)(3-bpmp)(H(2)O)(4)](n) coordination polymer chains. The chain motifs are oriented parallel to [10]. Individual chains are connected into supra-molecular layers via O-H?N and O-H?O hydrogen-bonding mechanisms.

Crystal structures of three co-crystals of 1,2-bis-(pyridin-4-yl)ethane with 4-alk-oxy-benzoic acids: 4-eth-oxy-benzoic acid-1,2-bis-(pyridin-4-yl)ethane (2/1), 4-n-propoxybenzoic acid-1,2-bis(pyridin-4-yl)ethane (2/1) and 4-n-but-oxy-benzoic acid-1,2-bis-(pyridin-4-yl)ethane (2/1).

Project description:The crystal structures of three hydrogen-bonded co-crystals of 4-alk-oxy-benzoic acid-1,2-bis-(pyridin-4-yl)ethane (2/1), namely, 2C9H10O3·C12H12N2, (I), 2C10H12O3·C12H12N2, (II), and 2C11H14O3·C12H12N2, (III), have been determined at 93, 290 and 93?K, respectively. In (I), the asymmetric unit consists of one 4-eth-oxy-benzoic acid mol-ecule and one half-mol-ecule of 1,2-bis-(pyridin-4-yl)ethane, which lies on an inversion centre. In (II) and (III), the asymmetric units each comprise two crystallographically independent 4-alk-oxy-benzoic acid mol-ecules and one 1,2-bis-(pyridin-4-yl)ethane mol-ecule. In each crystal, the two components are linked by O-H?N hydrogen bonds, forming a linear hydrogen-bonded 2:1unit of the acid and the base. Similar to the structure of 2:1 unit of (I), the units of (II) and (III) adopt nearly pseudo-inversion symmetry. The 2:1 units of (I), (II) and (III) are linked via C-H?O hydrogen bonds, forming tape structures.

Project description:The cation of the salt, [Mn(2)(C(14)H(14)N(4))(3)(H(2)O)(2)](ClO(4))(4), lies on a center of inversion, the center lying midway along the ethyl-ene chain of the bridging N,N'-bis-(2-pyridylmethyl-ene)ethane-1,2-diamine ligand. The Mn atom is chelated by two atoms N atoms of this bridging ligand, and is also coordinated by four N atoms of another ligand. The Mn atom is seven-coordinated in a penta-gonal-bipyramidal environment. The crystal structure displays inter-molecular ?-? inter-actions between adjacent pyridine rings, with a shortest centroid-centroid distance of 3.784?(3)?Å. The perchlorate is linked to the dinuclear cation by O-H?O hydrogen bonds.

Bis{?-2,2'-[1,1'-(ethane-1,2-diyldinitrilo)diethyl-idyne]diphenolato}bis-[(benzoato-?O)manganese(III)] dihydrate.

Project description:The title compound, [Mn(2)(C(18)H(18)N(2)O(2))(2)(C(7)H(5)O(2))(2)]·2H(2)O, was synthesized by the reaction between manganese(II) benzoate and the Schiff base generated in situ by the condensation of ethane-1,2-diamine and o-hydroxy-aceto-phen-one. The Jahn-Teller-distorted manganese(III) ions of the centrosymmetric dimer are connected through phen-oxy bridges. Hydrogen-bonding inter-actions between the uncoord-in-ated C=O of the benzoate and uncoordinated water mol-ecules link the dimers into a chain running parallel to the c axis.
