Tetra-aqua-bis[?-N-(5-nitro-2-oxido-benzyl-idene)glycylglycinato]manganese(II)dinickel(II) tetra-hydrate.

ABSTRACT: The two unique Ni(II) atoms of the title complex, [MnNi(2)(C(11)H(8)N(3)O(6))(2)(H(2)O)(4)]·4H(2)O, have a slightly distorted square-planar coordination environment with a tetra-dentate N-(5-nitro-2-oxidobenzyl-idene)glycylglycinate Schiff base trianion. The Ni(II) atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxyl-ate O atom. The Mn(II )atom is connected via the carboxyl-ate groups, forming a hetero-trinuclear Ni(II)-Mn(II)-Ni(II) system. The Mn(II) atom is six-coordinated in an octa-hedral geometry by four O atoms from two carboxyl-ate groups and four water mol-ecules. The Ni(II)-Mn(II)-Ni(II) hetero-trinuclear mol-ecules are stacked in the crystal and cross-linked through O-H?O hydrogen bonds.

Tetra-aqua-bis-[5-(pyridin-3-yl)tetra-zolido-?N?]manganese(II) tetra-hydrate.

Project description:The title compound, [Mn(C?H?N?)?(H?O)?]·4H?O, was obtained by the solution reaction of MnCl? and 3-(2H-tetra-zol-5-yl)pyridine. The Mn(II) atom, located on an inversion center, shows a slightly distorted octa-hedral geometry and is coordinated by two pyridine N atoms from two 5-(pyridin-3-yl)tetra-zolide ligands occupying trans positions and four water mol-ecules. In the crystal, the mononuclear complex mol-ecules and solvent water mol-ecules are connected into a three-dimensional framework by O-H?N and O-H?O hydrogen bonds.

Tetra-aqua-(2,2'-bipyridine-κN,N')manganese(II) di-μ-aqua-bis-[aqua-(2,2'-bipyridine-κN,N')(5-sulfonatoisophthalato-κO)manganate(II)] tetra-hydrate.

Project description:The crystal structure of the title salt, [Mn(C(10)H(8)N(2))(H(2)O)(4)][Mn(2)(C(8)H(3)O(7)S)(2)(C(10)H(8)N(2))(2)(H(2)O)(4)]·4H(2)O, consists of mononuclear manganese(II) cations, dinuclear manganate(II) dianions and uncoordinated water mol-ecules. The dianion is located about an inversion center; the Mn(II) atom is coordinated by a 2,2'-bipyridine ligand, a sulfonatoisophthalate group, a water mol-ecule along with two bridging water mol-ecules in an octa-hedral geometry. The cation lies on a twofold rotation axis; the Mn(II) atom is coordinated by four water mol-ecules and a chelating 2,2'-bipyridine ligand in a distorted octa-hedral geometry. A partially overlapped arrangement between the bipyridine ligands and the aromatic ring of the sulfoisophthalate group of adjacent anions is observed; the distance (3.357 Å) indicates π-π stacking. Hydrogen bonds, with the water mol-ecules serving as hydrogen-bond donors, lead to a three-dimensional network architecture.

Project description:In the title complex, {[NaNi(C(9)H(2)NO(8))(H(2)O)(7)]·4H(2)O}(n), the Ni(II) atom has a distorted octa-hedral coordination, defined by five O atoms from five water mol-ecules and one O atom from one 5-nitro-benzene-1,2,3-tricarboxyl-ate ligand. The Na cation is coordinated by six water O atoms in an irregular trigonal-prismatic geometry. There are seven coordinated water mol-ecules in the asymmetic unit. The Ni and Na atoms are linked by water bridges, forming infinite chains, which are connected by strong O-H?O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules into a three-dimensional network.

Tetra-aqua-bis-[4-(4H-1,2,4-triazol-4-yl)benzoato-?N]manganese(II) deca-hydrate.

Project description:In the title compound, [Mn(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·10H(2)O, the Mn(II) ion is coordinated by two N atoms from two 4-(4H-1,2,4-triazol-4-yl)benzoate ligands and four water mol-ecules in a distorted octa-hedral geometry. The Mn(II) ion and two coordinated water mol-ecules lie on a twofold rotation axis. The water mol-ecules are involved in O-H?N and O-H?O hydrogen bonds with the triazole N atoms and carboxyl-ate O atoms, yielding a three-dimensional supra-molecular network. ?-? inter-actions between the benzene rings [centroid-centroid distance = 3.836?(9)?Å] are observed.

?-4,4'-Diazenediyldiphthalato-?O:O-bis-[penta-aqua-manganese(II)] tetra-hydrate.

Project description:The dinuclear complex in the title compound, [Mn(2)(C(16)H(6)N(2)O(8))(H(2)O)(10)]·4H(2)O, lies on an inversion center. Two delocalized carboxyl-ate groups are each connected in a monodentate fashion to two similar penta-aqua-manganese units, whereas the other two localized carboxyl-ate groups are uncoordinated. The metal ion has octa-hedral coordination, with the O atom of a carboxyl-ate group and three coordinated water mol-ecules forming the equatorial plane [Mn-O(COO) = 2.143?(4)?Å] and two water mol-ecules occupying the axial positions. The architecture is further consolidated by extensive hydrogen bonds for which coordinated water mol-ecules serve as donors or acceptors.

Project description:In the polymeric title compound, {[Mn(2)(SO(4))(2)(C(30)H(36)N(6))(H(2)O)(2)]·6H(2)O}(n), the two Mn(2+) ions are bridged by two sulfate anions to form dinuclear complexes, and these dinuclear species are linked by the hexa-dentate ligand N,N,N',N'-tetra-kis(2-pyridylmeth-yl)hexane-1,6-diamine (tphn), forming a one-dimensional chain structure running in the [101] direction. The repeat unit of the polymer, Mn(2)(SO(4))(2)(H(2)O)(2)(tphn), is disposed about a twofold axis passing through the centre of the dinuclear unit. The coordination geometry around the Mn centre is distorted octa-hedral. Two methylene groups are each disordered equally over two positions.

catena-Poly[[[tetra-aqua-cadmium(II)]-?-4,4'-bipyridine] fumarate tetra-hydrate].

Project description:In the crystal structure of the title compound, [Cd(C(10)H(8)N(2))(H(2)O)(4)](C(4)H(2)O(4))·4H(2)O, the Cd(II) atom, on an inversion centre, is six-coordinated by four O atoms from four water mol-ecules and two N atoms from 4,4'-bpy mol-ecules in a distorted octa-hedral coordination geometry. Weak C-H?O inter-actions between uncoordinated carboxyl-ate O atoms of fumaric acid and water mol-ecules contribute to the crystal packing stability.

Tetra-aqua-tetra-manganese(II) catena-[germanodihydroxidodi(hydrogen-phosphate)diphosphate].

Project description:The title compound, Mn(4)(H(2)O)(4)[Ge(OH)(2)(HPO(4))(2)(PO(4))(2)], was synthesized by the solvothermal method. Its crystal structure is isotypic with the iron and cobalt analogues [Huang et al. (2012 ?). Inorg. Chem.51, 3316-3323]. In the crystal structure, the framework is built from undulating manganese phosphate sheets parallel to (010) inter-connected by GeO(6) octa-hedra (at the inversion center), resulting in a three-dimensional network with eight-membered ring channels into which all the protons point. The undulating manganese phosphate sheet consists of zigzag manganese octa-hedral chains along [10-1], built from MnO(4)(OH)(OH(2)) octa-hedra and MnO(5)(OH(2)) octa-hedra by sharing their trans or skew edges, which are inter-connected by PO(3)(OH) and PO(4) tetra-hedra via corner-sharing. The crystal structure features extensive O-H?O hydrogen-bonding inter-actions.

Discrete water clusters in tetra-?-cyanido-tetra-cyanidobis(1,4,7-triisopropyl-1,4,7-triaza-cyclo-nona-ne)dicopper(II)dinickel(II) tetra-hydrate.

Project description:The title tetra-cyanido-nickelate-copper complex, [Cu?Ni?(CN)?(C??H??N?)?]·4H?O, was synthesized by self-assembly using potassium tetracyanidonickelate(II) and dichlorido(1,4,7-triisopropyl-1,4,7-triazacyclononane)copper(II). The asymmetric unit contains half of a complex mol-ecule and two water mol-ecules. The entire complex has -1 symmetry and contains Ni(II) in a slightly distorted square-planar and Cu(II) in a square-pyramidal coordination environment. The crystal packing shows a discrete tetra-mer water cluster. Within the cluster, the four water mol-ecules are fully coplanar and each water monomer acts both as single O-H?O and O-H?N hydrogen-bond donor and acceptor.
