In the title compound, (NH4)Na(PO3F)·H2O, the distances and the angles are normal. Na is coordinated in a distorted octahedral environment by one F atom, four anion O atoms and one water O atom. Fluorine, as in other structures, is not involved in two-centre hydrogen bonds. There are two-centre O—H...O and two- and three-centre N—H...O hydrogen bonds in the crystal structure.

In the title compound, [Cu(ClO4)2(C20H40N4)], the CuII ion has a tetragonally distorted octahedral environment, with the four N atoms of the macrocyclic ligand in equatorial positions and the O atoms of two perchlorate groups in axial positions. The CuII ion is situated on an inversion centre. The macrocyclic ligand adopts its most stable trans-III conformation. The long axial Cu—O bond is the result of the Jahn–Teller effect. The crystal structure is stabilized by intramolecular hydrogen bonds between secondary N—H and the O atoms of the perchlorate groups.

In the title compound, [( t BuSiMe2O)2MoO2(2,2′-bipyridine)] or [Mo(C6H15OSi)2O2(C10H8N2)], the MoVI atom has a distorted octahedral environment with the siloxy substituents occupying the trans positions. The complex contains a rare (R 3SiO)2 MO2 (M = Mo, W) structural motif and was formed in a reaction between sodium molybdate and tert-butyldimethylsilyl chloride in the presence of 2,2-bipyridine. In the crystal, neighbouring molecules are linked by C—H...O=Mo hydrogen bonds, forming chains propagating along the a-axis direction.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.

In the crystal structure of the mononuclear title compound, [Mn(NCS)2(C10H8N2)2]·C10H8N2, the MnIIcation is coordinated in an all-cisconfiguration by two N-bound thiocyanate anions and two 2,2′-bipyridine ligands within a slightly distorted octahedral environment. The asymmetric unit consists of one MnIIcation, two thiocyanate anions and two 2,2′-bipyridine ligands, as well as two non-coordinating 2,2′-bipyridine ligands that are each located on centres of inversion. In the crystal structure, the discrete [Mn(NCS)2(C10H8N2)2] complex molecules are arranged in such a way that cavities are formed, in which the solvent 2,2′-bipyridine molecules are located. Apart from van der Waals forces, there are no remarkable intermolecular interactions present in the crystal structure.

In the title compound, [Zn4(C11H9N2O2)4(C7H5O2)4]·2(CH3)2CO·CH3OH, the tetranuclear molecule lies on a fourfold inversion axis. ZnIIions and μ3-O atoms in the cubane core occupy alternating vertices, forming two interpenetrating tetrahedra. Each ZnIIion is further coordinated by two N atoms from two different (py)2C(OH)O ligands (py is pyridyl) and one O atom from a monodentate benzoate ligand, forming a distorted octahedral environment. The (py)2C(OH)O ligand acts in an η1:η3:η1:μ3manner, forming two five-membered ZnNCCO chelating rings with two different ZnIIatoms sharing a common C—O bond, and an alkoxide-type bond to a third ZnIIion. There are four symmetry-related intramolecular O—H...O hydrogen bonds between the two types of ligands. In the asymmetric unit, there is a half-occupancy acetone solvent molecule and a half-occupancy methanol solvent molecule that lies on a twofold rotation axis.

In the title compound, [Cd(C8H7O3)2(C14H12N2)], the CdIIion is coordinated by two N atoms from a 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and four O atoms from two 2-methoxybenzoate anions in a distorted octahedral environment. Two O atoms of one bidentate 2-methoxybenzoate ligand are each disordered over two positions, with site-occupancy factors of 0.579 (4) and 0.421 (4). In the crystal, molecules are linked by C—H...O hydrogen bonds, forming a two-dimensional network lieing parallel to thebcplane. The crystal packing is further stablized by π–π stacking interactions between the dmphen rings of neighboring molecules, with distances between their parallel dmphen ring planes of 3.517 (3) and 3.610 (3) Å.
