Dichloridobis[(S)-2-hydroxy-propion-amide-?O,O']manganese(II).

ABSTRACT: In the title compound, [MnCl(2)(C(3)H(7)NO(2))(2)], the Mn(II) ion is bound to two Cl atoms and to four O atoms from two lacta-mide mol-ecules which act as bidentate ligands, giving rise to a highly distorted octa-hedral coordination geometry. The axial positions are occupied by one Cl atom and one O (hydr-oxy) atom. The values of the cis bond angles at the Mn atom are in the range 72.33?(5)-100.17?(6)°. Of the two possible coordination modes (N,O- or O,O-bidentate) in metal complexes with lacta-mide or its derivatives described in the literature, the title compound exhibits the O,O-bidentate mode. In the crystal structure, monomeric manganese(II) complexes are linked by several N-H?Cl, O-H?Cl and O-H?O hydrogen bonds, generating a three-dimensional network.

cis-Dichloridobis[2-(hydroxy-meth-yl)tetra-hydro-furan-?O,O']manganese(II).

Project description:The structure of the title compound, [MnCl(2)(C(5)H(10)O(2))(2)], was solved from low-temperature data collected at 100?(2)?K. The asymmetric unit contains one half-mol-ecule with the Mn(II) ion located on a twofold axis. A distorted octa-hedral environment around the Mn atom is formed by two ether and two hydroxyl O atoms of two 2-(hydroxy-methyl)tetra-hydro-furan ligands, and by two chloride ions. The chelating tetra-hydro-furan ligands, which form five-membered rings, are cis oriented. The crystal structure is stabilized by hydrogen bonding between the coordinated OH groups and the chloride ions.

Diaqua-dichloridobis(pyridine-?N)manganese(II).

Project description:The molecular title compound, [MnCl(2)(C(5)H(5)N)(2)(H(2)O)(2)], lies about an inversion centre. The Mn(II) atom is in an all-trans octa-hedral environment defined by two water mol-ecules, two chloride anions and two pyridine ligands. An inter-molecular hydrogen-bonding inter-action between a water mol-ecule and a chloride anion bonded to an adjacent Mn(II) atom generates an eight-membered ring. The crystal packing exhibits two inter-molecular ?-? stacking inter-actions between the aromatic rings, with centroid-centroid distances of 3.485?(12) and 3.532?(12)?Å.

cis-Dichloridobis-(5,5'-dimethyl-2,2'-bipyridine)-manganese(II) 2.5-hydrate.

Project description:The metal site in the title compound [MnCl(2)(C(12)H(12)N(2))(2)]·2.5H(2)O has a distorted octa-hedral geometry, coordinated by four N atoms of two 5,5'-dimethyl-2,2'-dipyridine ligands and two Cl atoms. Two and a half water molecules of hydration per complex unit are observed in the crystal structure. The compounds extend along the c axis with O-H?Cl, O-H?O, C-H?Cl and C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.70?(2)?Å] contributing substanti-ally to the crystal packing. The Mn and one of the water O atoms, the latter being half-occupied, are located on special positions, in this case a rotation axis of order 2.

cis-Dichloridobis(di-2-pyridyl-amine-?N,N')manganese(II).

Project description:In the title complex, [MnCl(2)(C(10)H(9)N(3))(2)], the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)Cl(2) octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (dpa) ligands and two Cl(-) anions. In the crystal, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.3?(2) and 30.9?(2)°. The complex mol-ecules are stacked in columns along the c axis and are connected by inter-molecular N-H?Cl hydrogen bonds, forming a three-dimensional network. Weak inter- and intra-molecular ?-? inter-actions are present between the pyridine rings, the shortest centroid-centroid distance being 4.406?(3)?Å.

cis-Dichloridobis(1,10-phenanthroline-?N,N')manganese(II)-2,6-dihydroxy-benzoic acid-water (2/1/4).

Project description:In the crystal structure of the title compound, [MnCl(2)(C(12)H(8)N(2))(2)]·0.5C(7)H(6)O(4)·2H(2)O, the Mn(II) complex assumes a distorted octa-hedral geometry formed by two chloride anions and two phenanthroline (phen) ligands. The 2,6-dihydroxy-benzoic acid mol-ecule is disordered about an inversion center. The face-to-face separations of 3.540?(11) and 3.429?(8)?Å between parallel phen ligands indicate the existence of ?-? stacking between adjacent Mn(II) complexes. Uncoordinated water mol-ecules are linked with complex and dihydroxy-benzoic acid mol-ecules via O-H?Cl and O-H?O hydrogen bonds.

catena-Poly[[[tetra-aqua-manganese(II)]-?-4,4'-bipyridine] bis-(3-hydroxy-cinnamate) dihydrate].

Project description:The title compound, {[Mn(C(10)H(8)N(2))(H(2)O)(4)](C(9)H(7)O(3))(2)·2H(2)O}(n), was obtained by the hydro-thermal reaction of manganese chloride with mixed 3-hydroxy-lcinnamic acid (H(2)L) and 4,4'-bipyridine (4,4'-bipy) ligands. The structure contains [Mn(C(10)H(8)N(2))(H(2)O)(4)](2+) cations with the Mn(II) atoms lying on a centres of inversion and bridged into a linear chain along the a axis by 4,4'-bipy ligands, surrounded by HL(-) anions and uncoordinated water mol-ecules. Extensive O-H?O hydrogen-bonding and weak ?-? inter-actions [centroid-centroid distance = 3.7572 ?(3)?Å] between the constituents lead to the formation of a three-dimensional supra-molecular network.

Dichloridobis(thio-urea-?S)nickel(II).

Project description:The title complex, [NiCl(2)(CH(4)N(2)S)(2)], has been synthesized from the previously reported (diamino-methyl-idene)sulfonium chloride-thio-urea (3/2) salt [Zouihri (2012b ?). Acta Cryst. E68, o257]. The Ni(II) ion is coordinated in a distorted tetra-hedral geometry by two mol-ecules of thio-urea [Ni-S = 2.3079?(7) and 2.3177?(6)?Å] and two chloride anions [Ni-Cl = 2.2516?(7) and 2.2726?(7)?Å]. The bond angles at the Ni atom lie between 96.69?(2) and 115.40?(3)°, while the dihedral angle between the mean planes of the two thio-urea ligands is 6.36?(15)°. The crystal structure is characterized by intra- and inter-molecular N-H?Cl hydrogen bonds, which lead to the formation of two-dimensional networks lying parallel to the ab plane. The networks are linked via classical N-H?Cl and N-H?S hydrogen bonds, forming a three-dimensional arrangement.
