Diaqua-iodido(2,3,5,6-tetra-2-pyridyl-pyrazine-?N,N,N)manganese(II) iodide monohydrate.

ABSTRACT: The asymmetric unit of the title compound, [MnI(C(24)H(16)N(6))(H(2)O)(2)]I·H(2)O, consists of a cationic Mn(II) complex, an I(-) anion and a solvent water mol-ecule. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted octa-hedral environment defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine (tppz) ligand, one I(-) anion and two O atoms of two water ligands. The dihedral angles between the pyridyl rings [maximum deviation = 0.034?(6)?Å] and their carrier pyrazine ring [maximum deviation = 0.020?(6)?Å] are 26.5?(2) and 27.0?(2)° for the coordinated pyridyl rings, and 51.3?(3) and 43.2?(2)° for the uncoordinated pyridyl rings. Inter-molecular O-H?O, O-H?N and O-H?I hydrogen bonds stabilize the crystal structure.

[?-2,3,5,6-Tetra-kis(2-pyrid-yl)pyrazine-?N,N,N:N,N,N]bis-[diaqua(dihydrogen m-phenylene-diphospho-nato-?O)nickel(II)] dihydrate.

Project description:The title compound [Ni(2)(C(6)H(6)O(6)P(2))(2)(C(24)H(16)N(6))(H(2)O)(4)]·2H(2)O or [Ni(2)(tpyprz)(1,3-HO(3)PC(6)H(4)PO(3)H)(2)(H(2)O)(4)]·2H(2)O [tpyprz = tetra-kis-(2-pyrid-yl)pyrazine, C(24)H(16)N(6)] is a binuclear complex with a crystallographic inversion center located at the center of the pyrazine ring. The equivalent nickel(II) sites exhibit a distorted {NiO(3)N(3)} octa-hedral coordination, with the three nitro-gen donors of each terminus of the tpyprz ligand in a meridional orientation. An aqua ligand occupies the position trans to the pyrazine nitro-gen donor, while the second aqua ligand is trans to the oxygen donor of the dihydrogen-1,3-phenyl-diphospho-nate ligand. The Ni-O and Ni-N bond lengths fall in the range 2.011?(3) to 2.089?(3)?Å. The protonation sites on the organo-phospho-nate ligand are evident in the significantly longer P-O bonds compared to the unprotonated sites. In the crystal structure, the complex mol-ecules and the solvent water mol-ecules are linked into a three-dimensional hydrogen-bonded framework through O-H?O inter-actions between the aqua ligands, the protonated organo-phospho-nate oxygen atoms and the water mol-ecules of crystallization. Intra-molecular ?-stacking between the phenyl group of the phospho-nate ligand and a pyridyl group of the tpyprz ligand, at a distance of 3.244?(5)?Å between ring centroids, is also observed.

Crystal structure of a tetra-kis-substituted pyrazine compound: 2,3,5,6-tetra-kis-(bromo-meth-yl)pyrazine.

Project description:The title compound, C8H8Br4N2, crystallizes in the enanti-omorphic-defining space group P41212 and has a refined Flack x parameter of 0.04?(4). In the asymmetric unit, there are two half-mol-ecules; the whole mol-ecules (A and B) are generated by twofold rotation symmetry. In mol-ecule A, the twofold axis is normal to the pyrazine ring passing through the centre of the ring, while in mol-ecule B, the twofold rotation axis lies in the plane of the pyrazine ring bis-ecting the C-C aromatic bonds. The two mol-ecules are pseudo-mirror images of one another, and the best fit of the two mol-ecules was obtained for inverted mol-ecule B on mol-ecule A, with an r.m.s. deviation of 0.1048?Å and a maximum deviation of any two equivalent atoms of 0.2246?Å. In the crystal, the A mol-ecules are linked by weak C-H?Br hydrogen bonds and Br?Br inter-actions [3.524?(3)?Å], forming a three-dimensional framework. The B mol-ecules are also linked by weak C-H?Br hydrogen bonds and Br?Br inter-actions [3.548?(3)?Å], forming a three-dimensional network that inter-penetrates the network of A mol-ecules.

Project description:The title complex, [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)][Ni(CN)(4)]·C(4)H(8)O·H(2)O, consists of a cationic [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) unit, an anionic [Ni(CN)(4)](2-) unit, one uncoordinated water and one tetra-hydro-furan mol-ecule. In the cationic unit, the Ni(2+) atom is coordinated by four N atoms and two O atoms from two 1,10-phenanthroline ligands and two water mol-ecules in a distorted octa-hedral coordination environment. In the anionic unit, the Ni(2+) atom is in a square-planar coordination by four C atoms from four monodentate terminal cyanide ligands. O-H⋯N and O-H⋯O hydrogen bonds link neighboring cationic and anionic units, forming a three-dimensional supra-molecular network. The inter-stitial tetra-hydro-furan mol-ecule is independently disordered over two sites in a 1:1 ratio.
