(?-2,2'-Bipyrimidine-?N,N:N,N)bis-[triaqua-(sulfato-?O)manganese(II)].

ABSTRACT: The title complex, [Mn(2)(SO(4))(2)(C(8)H(6)N(4))(H(2)O)(6)], is the second monoclinic polymorph [De Munno et al. (1995 ?). Inorg. Chem.34, 408-411; Hong et al. (1996 ?). Polyhedron, 15, 447-452]. The asymmetric unit contains two crystallographically independent half-mol-ecules of the binuclear Mn(II) complex; an inversion centre is located at the centroid of each complex. The two Mn(II) atoms in each complex mol-ecules are bridged by a bis-chelating 2,2'-bipyrimidine (bpym) ligand and each Mn(II) atom is six-coordinated in a considerably distorted octa-hedral environment defined by two N atoms of the bridging bpym ligand and four O atoms from one sulfato anionic ligand and three water mol-ecules. In the crystal, the complex mol-ecules are linked by O-H?O hydrogen bonds between the water and sulfato ligands, forming a three-dimensional network.

Project description:The asymmetric unit of the title compound, [Mn(CH(3)CN)(C(8)H(6)N(4))(2)(H(2)O)][Mn(C(8)H(6)N(4))(2)(H(2)O)(2)](ClO(4))(4)·2H(2)O, contains two distinct cationic Mn(II) complexes, four perchlorate anions and two solvent water mol-ecules. In the two complexes, both Mn(II) ions are six-coordinated in a distorted octa-hedral environment, but one Mn ion has a cis-N(5)O coordination geometry defined by four N atoms of the two chelating 2,2'-bipyrimidine (bpym) ligands, one N atom of a coordinating acetonitrile mol-ecule and one O atom of a water ligand, whereas the other Mn ion has a cis-N(4)O(2) coordination geometry defined by four N atoms of the two bpym ligands and two O atoms of water ligands. In the crystal structure, the complex mol-ecules, anions and solvent water mol-ecules are linked by inter-molecular O-H?O and O-H?N hydrogen bonds. Three of the four perchlorate anions are disordered over two sets of sites in different ratios.

Bis(?-pyridinium-2-carboxyl-ato-?O:O')bis-[triaqua-(sulfato-?O)manganese(II)].

Project description:The asymmetric unit of the title compound, [Mn(2)(SO(4))(2)(C(6)H(5)NO(2))(2)(H(2)O)(6)], comprises half of a centrosymmetric dimer.

In the crystal, mol-ecules are connected through N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by inter-molecular ?-? inter-actions [centroid-centroid distance = 3.842?(2)?Å].

cis-Bis(2,2'-bipyrimidine-?N,N)di-iodidomanganese(II).

Project description:The asymmetric unit of the title complex, [MnI(2)(C(8)H(6)N(4))(2)], contains one half of a neutral Mn(II) complex, with the entire molecule completed by the application of twofold symmetry. The Mn(II) ion is six-coordinated in a distorted octa-hedral environment defined by four N atoms of the two chelating 2,2'-bipyrimidine (bpym) ligands and two I(-) anions in a cis-N(4)I(2) coordination geometry. The dihedral angle between the least-squares planes of the two bpym ligands (r.m.s deviation for all non-H atoms = 0.063?Å) is 85.04?(6)°. In the crystal, complex mol-ecules are connected by C-H?N and C-H?I hydrogen bonds, forming a three-dimensional network. Mol-ecules are stacked in columns along the a axis. Along the c axis, successive mol-ecules stack in the opposite directions.

Poly[[(μ-2,2'-bipyrimidine-κN,N:N,N)(μ-sulfato-κO:O')zinc(II)] monohydrate].

Project description:In the title compound, {[Zn(SO(4))(C(8)H(6)N(4))]·H(2)O}(n), the Zn(II) atom is in a distorted octa-hedral environment. The Zn(II) atoms are bridged by both 2,2'-bipyrimidine and sulfate ligands, thus forming a three-dimensional polymeric metal-organic solid that contains uncoordinated water mol-ecules in the inter-stitial space. O-H⋯O hydrogen bonding consolidates the crystal structure.

μ-(2,2'-Bipyrimidine)-bis-[dichlorido-palladium(II)] dimethyl-formamide monosolvate.

Project description:In the title compound, [Pd(2)Cl(4)(C(8)H(6)N(4))]·C(3)H(7)NO, the two Pd(2+) cations have a distorted square-planar coordination sphere and are bridged by a bis-bidentate 2,2'-bipyrimidine ligand. Two terminal chloride anions are also bonded to each of the Pd(2+) cations. The dinuclear complex and the dimethylformamide solvate molecule lie on the inter-section of a twofold rotation axis and a mirror plane, with disorder present in the solvate mol-ecule. There is a slight distortion from the square-planar metal geometry, as indicated by the bite angles of 81.77 (13)° and 91.63 (5)°. The C and O atoms of the solvent mol-ecule are disordered over two sets of sites of equal occupancy.

cis-Aqua-bis-(2,2'-bipyrimidine-?N,N)iodidomanganese(II) iodide dihydrate.

Project description:The asymmetric unit of the title compound, [MnI(C(8)H(6)N(4))(2)(H(2)O)]I·2H(2)O, contains a cationic Mn(II) complex, an I(-) anion and two solvent water mol-ecules. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted octa-hedral environment defined by four N atoms of the two chelating 2,2'-bipyrimidine (bpym) ligands, one I(-) anion and one O atom of a water ligand. As a result of the different trans effects of the I and O atoms, the Mn-N bond trans to the I atom is slightly longer than the Mn-N bond trans to the O atom. The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.088?(4)?Å] is 76.48?(6)°. In the crystal, the complex cation, the anion and the solvent water mol-ecules are linked by inter-molecular O-H?O, O-H?I and O-H?N hydrogen bonds.
