Distorted Octahedral Coordination Environment

The title compound, [Re(C8H6N4)(C25H22P2)(CO)3]CF3SO3·H2O, crystallizes with one [Re(C8N4H6){P(Ph)2CH2P(Ph)2}(CO)3]+cation, where Ph is a phenyl group, one CF3SO3−anion and one water molecule of hydration. The three C atoms of thefacialoriented carbonyl groups, two N atoms from the bipyrazine ligand and one P atom from the (bis)diphenylphosphanylmethane ligand define a distorted octahedral coordination environment about the central ReIatom. The Re—Ccarbonylbond lengthtransto the P atom is longer than the the two Re—Ccarbonylbond lengths in the plane with the bipyrazine ligand. Hydrogen-bonding interactions between the solvent water molecule and the cation, as well as weak C—H...O interactions, consolidate a three-dimensional network structure.

The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octahedral coordination environment defined by three chlorido ligands, an oxygen atom from a water molecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N—H...O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H2O)Cl3(C2O4)]−anion. Neighbouring stannate(IV) anions are linked through O—H...O hydrogen bonds involving the water molecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N—H...Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.

The CoIIion in the title complex, [Co(SO4)(C13H8N4)(H2O)2]n, has a slightly distorted octahedral coordination environment formed by two O atoms from two symmetry-related bridging sulfate ligands, two N atoms from a bis-chelating 1H-imidazo[4,5-f][1,10]phenanthroline (IPL) ligand and two O atoms from coordinated water molecules. The bridging sulfate ligands connect CoIIions to form a one-dimensional chain along theb-axis direction. In the crystal structure, intermolecular O—H...O, O—H...N and N—H...O hydrogen bonds link the chains into a three-dimensional network.

The title bromide salt, [Cr{CO(NH2)2}6](Cr2O7)Br·H2O, is isotypic to the corresponding chloride salt. Within the complex cation, the CrIIIatom is coordinated by six O atoms of six urea ligands, displaying a slightly distorted octahedral coordination environment. The Cr—O bond lengths involving the urea ligands are in the range 1.9534 (13)–1.9776 (12) Å. The Cr2O72−anion has a nearly staggered conformation, with a bridging angle of 130.26 (10)°. The individual components are arranged in rows extending parallel to [100]. The Br−anion links the complex cation, as well as the solvent water molecule, through N—H...Br and O—H...Br hydrogen-bonding interactions. The supramolecular architecture also includes N—H...O and O—H...O hydrogen bonding between urea N—H and water O—H donor groups and the O atoms of the Cr2O72−anion as acceptor atoms, leading to a three-dimensional network structure.

In the structure of the title salt, [Co(C6H6N2)2(H2O)2](BF4)2, the CoIIatom is located on an inversion centre. The transition metal is in a slightly distorted octahedral coordination environment, defined by the cyano N atoms of four hex-3-enedinitrile ligands in equatorial positions and the O atoms of two water molecules in axial positions. The bridging mode of the hex-3-enedinitrile ligands leads to the formation of cationic chains extending parallel to [1-10]. The BF4−counter-anion is disordered over two sets of sites [occupancy ratio = 0.512 (19):0.489 (19)]. It is located in the voids between the cationic chains and is connected to the aqua ligands of the latter through O—H...F hydrogen bonds. One methylene H atom of the hex-3-enedinitrile ligand forms another and weak C—H...O hydrogen bond with a water O atom of a neighbouring chain, thus consolidating the three-dimensional network structure.
