A second monoclinic polymorph of bis-(2,2'-bipyridine-?N,N')diiodido-manganese(II).

ABSTRACT: The Mn(II) ion in the title complex, [MnI(2)(C(10)H(8)N(2))(2)], is six-coordinated in a distorted cis-N(4)I(2)Mn octa-hedral environment by four N atoms of the two chelating 2,2'-bipyridine ligands and two iodide anions. As a result of the different trans effects of the N and I atoms, the Mn-N bonds trans to the I atom are slightly longer than the Mn-N bonds trans to the N atom. The dihedral angle between the approximately planar ligands [maximum deviation = 0.064?(7)?Å] is 75.0?(1)°. Numerous inter- and intra-molecular ?-? inter-actions between the pyridyl rings are present, the shortest centroid-centroid distance being 3.905?(5)?Å. The structure reported herein represents a new monoclinic polymorph of the previously reported monoclinic (P2(1)/c) form [Ha (2011 ?). Z. Kristallogr. New Cryst. Struct.226, 187-188].

?-Oxalato-bis-[bis-(2,2'-bipyridine)-manganese(II)] bis(perchlorate) 2,2'-bipyridine solvate.

Project description:The unit cell of the title compound, [Mn(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·C(10)H(8)N(2), consists of a binuclear cation, two perchlor-ate anions, and one solvent 2,2'-bipyridine (bpy) mol-ecule. In the complex cation [Mn(2)(C(2)O(4))(C(10)N(2)H(8))(4)](2+), two Mn(II) atoms are bridged by a bis-(bidentate) oxalate ligand, each Mn(II) atom being further coordinated by two bpy ligands in a distorted octa-hedral geometry. The distance between the two six-coordinated metal atoms is 5.583?(1)?Å. ?-? stacking inter-actions [inter-planar distances between bpy rings = 3.739?(1)?Å] are essential to the supramolecular assembly. There are extensive inter-ionic C-H?O inter-actions between the cations and between the cation and anion. Three of the four perchlorate O atoms are disordered over two sets of sites with occupancy ratios of 0.852?(6):0.148?(6).

Bis(2,2'-bipyridine N,N'-dioxide)bis-(tri-cyano-methanido)manganese(II).

Project description:In the title complex, [Mn(C(4)N(3))(2)(C(10)H(8)N(2)O(2))(2)], the Mn(II) atom lies on an inversion center and is coordinated by two 2,2'-bipyridine N,N'-dioxide (dpdo) mol-ecules and two tricyano-methanide (tcm) ligands to form a distorted octa-hedral geometry. Weak inter-molecular C-H?O or C-H?N hydrogen bonds, involving either the O atom of the dpdo mol-ecule and the pyridyl H atom, or the N atom of the tcm anion and the pyridyl H atom, result in the formation of a three-dimensional network structure.

Bis[2-(hy-droxy-imino-meth-yl)phenolato]nickel(II): a second monoclinic polymorph.

Project description:The title compound, [Ni(C(7)H(6)NO(2))(2)], (I), is a second monoclinic polymorph of the compound, (II), reported by Srivastava et al. [Acta Cryst. (1967), 22, 922] and Mereiter [Private communication (2002) CCDC refcode NISALO01]. The bond lengths and angles are similar in both structures. The mol-ecule in both structures lies on a crystallographic inversion center and both have an inter-nal hydrogen bond. The title compound crystallizes in the space group P2(1)/c (Z = 2), whereas compound (II) is in the space group P2(1)/n (Z = 2) with a similar cell volume but different cell parameters. In both polymorphs, mol-ecules are arranged in the layers but in contrast to the previously published compound (II) where the dihedral angle between the layers is 86.3°, in the title polymorph the same dihedral angle is 29.4°. The structure of (I) is stabilized by strong intra-molecular O-H?O hydrogen bonding between the O-H group and the phenolate O atom.

Tetra-kis(?(2)-2,2-dimethyl-propanoato-?O,O')bis-[(pyridine-?N)copper(II)]: a monoclinic polymorph.

Project description:The structure of the dinuclear title complex, [Cu(2)(C(5)H(9)O(2))(4)(C(5)H(5)N)(2)], represents a monoclinic polymorph of the previously reported triclinic form [Blewett et al. (2006 ?). Acta Cryst. E62, m420-m422]. Each carboxyl-ate group is bidentate bridging and the distorted octa-hedral geometry about each Cu(II) atom is completed by a pyridine N atom and the other Cu atom [Cu?Cu = 2.6139?(7)?Å]. In the crystal, mol-ecules are connected into supra-molecular chains via ?-? inter-actions formed by the pyridine rings [centroid-centroid distance = 3.552?(3)?Å] and these are connected into a two-dimensional array in the ac plane by C-H?? contacts. One of the tert-butyl groups is disordered over two orientations in a 0.734?(6):0.266?(6) ratio.
