Diaqua-bis-(dimethyl sulfoxide-?O)bis(saccharinato-?N)cobalt(II).

ABSTRACT: The title complex, [Co(C(7)H(4)NO(3)S)(2)(C(2)H(6)OS)(2)(H(2)O)(2)], contains a Co(2+) cation in an octa-hedral coordination environment. The metal atom is surrounded by two different neutral ligands, namely dimethyl-sulfoxide (DMSO) and water, each coordinating through the O atom. The anionic saccharinate (sac; 1,1,3-trioxo-2,3-dihydro-1?(6),2-benzothia-zol-2-ide) ligand coordinates through the N atom. Each of the three similar ligand pairs is in a trans configuration with respect to each other. The Co atom lies on a crystallographic center of symmetry and the octa-hedral geometry is not significantly distorted. A short O-H?O hydrogen bond is present between a water H atom and the ketone O atom; two longer hydrogen bonds (intra- and inter-molecular) are also present between a water H and a sulfonic O atom, forming a supramolecular assembly through head-to-tail aggregation between adjacent complexes.

cis-Diaqua-bis-[dimethyl (phenyl-sulfonyl-imino)-phospho-nato]cobalt(II).

Project description:In the title diaqua-cobalt complex, [Co(C(8)H(11)NO(5)PS)(2)(H(2)O)(2)], the Co(II) atom is surrounded by six O atoms belonging to the phosphoryl and sulfonyl groups of two deprotonated chelate ligands and two additional O atoms from water mol-ecules which are in cis positions with respect to one another. The coordination environment of cobalt can be described as a distorted octa-hedron. O-H⋯O hydrogen bonds between the water and sulfonyl O atoms of neighboring mol-ecules form chains running parallel to [010]. Two methoxy groups attached to one phosphorus are disordered over two sets of sites in a 0.6:0.4 ratio.

Bis(dimethyl sulfoxide)-hydridobis(triphenyl-phosphane)cobalt(I).

Project description:The title compound, [CoH(C(18)H(15)P)(2)(C(2)H(6)OS)(2)], was synthesized by the reaction of chloridotris(triphenyl-phosphane)cobalt(I), [ClCo(PPh(3))(3)], in the presence of one equivalent potassium hydridotris(pyrazol-yl)borate in dimethyl sulfoxide. The structure displays a distorted trigonal-pyramidally coordinated cobalt(I) atom, with two phosphane ligands and one DMSO ligand in the equatorial plane. The coordination is completed by one further DMSO ligand and the anionic hydride in the axial positions.

Diaqua-bis[4-(dimethyl-amino)-benzoato]-?O,O';?O-(isonicotinamide-?N)cobalt(II).

Project description:The title Co(II) complex, [Co(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], contains two 4-dimethyl-amino-benzoate (DMAB) anions, one isonicotinamide (INA) ligand and two coordinated water mol-ecules. One of the DMAB anions acts as a bidentate ligand, while the other is monodentate. The four O atoms in the equatorial plane around the Co atom form a highly distorted square-planar arrangement, while the distorted octa-hedral coordination geometry is completed by the N atom of the INA ligand and the O atom of the second water mol-ecule in the axial positions. An intra-molecular O-H?O hydrogen bond between the monodentate-coordinated carboxyl group and a coordinated water mol-ecule results in a six-membered ring with an envelope conformation. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 4.29?(10)° for the monodentate ligand and 2.31?(13)° for the bidentate ligand, while the two benzene rings are oriented at a dihedral angle of 65.02?(5)°. The dihedral angles between the pyridine and benzene rings are 11.21?(5)° for the monodentate ligand and 74.60?(5)° for the bidentate ligand. In the crystal structure, inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link the mol-ecules into a supra-molecular structure.

Diaqua-bis(2,2'-biimidazole)cobalt(II) dichloride.

Project description:There are independent cations and four chloride anions in the crystal structure of the title complex, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)]Cl(2). In each cation, the Co(II) cation is coordinated by four N atoms from two biimidazole and two O atoms of two water mol-ecules; one Co atom is at a position of site symmetry m, the other at a position of site symmetry 2/m. All Cl(-) ions and water mol-ecules are also located on the mirror plane. Each structural unit is connected through O-H?Cl and N-H?Cl inter-molecular hydrogen bonds, forming a three-dimensional supramolecular structure.

Diaqua-bis-(propane-1,3-diamine)-copper(II) bis-[diamminetetra-kis-(thio-cyanato-?N)chromate(III)] dimethyl sulfoxide octa-solvate.

Project description:The ionic title complex, [Cu(C(3)H(10)N(2))(2)(H(2)O)(2)][Cr(NCS)(4)(NH(3))(2)]·8C(2)H(6)OS, consists of complex [Cu(dipr)(2)(H(2)O)(2)](2+) copper cations (dipr is propane-1,3-diamine), complex [Cr(NCS)(4)(NH(3))(2)](-) anions and uncoord-inated solvent dimethyl sulfoxide (DMSO) mol-ecules. All the metal atoms lie on crystallographic centers of symmetry. The cations are connected to the anions through N-H?O hydrogen bonds between the NH(3) mol-ecules of the anion and the water mol-ecules of the cation. The DMSO mol-ecules are involved in hydrogen-bonded linkage of the [Cr(NCS)(4)(NH(3))(2)](-) anions into supra-molecular chains through bridging O atoms. A network of hydrogen bonds as well as short S?S contacts [3.5159?(12) and 3.4880?(12)?Å] between the NCS groups of the complex anions link the mol-ecules into a three-dimensional supra-molecular network.

The tetra-hedral geometry is slightly distorted as is evident from the N-Zn-N bond angle of 113.85?(6)°, the O-Zn-O bond angle of 98.92?(6)° and O-Zn-N bond angles of 116.96?(6) and 103.93?(6)°. The Zn-N bond lengths are 1.9742?(15) and 2.0025?(16)?Å. The Zn-O bond lengths are 1.9806?(14)?Å and 1.9468?(14)?Å. The DMSO ligand coordinates through the lone pair of electrons on the O atom, as can be seen from the Zn-O-S bond angle of 131.30?(8)°.

Diaqua-bis[2-(benzyl-oxy)acetato]cobalt(II).

Project description:In the mononuclear title complex, [Co(C(9)H(9)O(3))(2)(H(2)O)(2)], each Co(II) atom is located on an inversion center and is hexa-coordinated by four O atoms from two benzyl-oxyacetate ligands [Co-O bond lengths = 2.0487 (9) and 2.1090 (9) Å] and two water mol-ecules [Co-O bond length = 2.0873 (9) Å] in a distorted octa-hedral geometry. In the crystal structure, inter-molecular hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance between phenyl rings = 3.692 (2) Å] link the mol-ecules into a supra-molecular structure.

Poly[hexa-?-acetato-bis-(dimethyl sulfoxide)-trimanganese(II)].

Project description:In the title complex, [Mn(3)(CH(3)CO(2))(6)(C(2)H(6)SO)(2)](n), the Mn(II) ions exhibit similar MnO(6) octa-hedral coordination geometries but with different coordination environments. One type of Mn(II) ion is surrounded by five acetate groups and a terminal dimethyl sulfoxide group, while the other lies on a twofold axis and is coordinated by six O atoms from three symmetry-related acetate ions. The acetate anions exhibit three independent bridging modes, which flexibly bridge the Mn(II) ions along the c-axis direction, forming an infinite chain structure; the chains are further inter-connected through weak C-H?O and C-H?S hydrogen-bonding inter-actions.
