The complex [Ni(pn)3][Fe(CN)5NO]·H2O (1) was synthesised by the reaction of [Ni(pn)3]Cl2 (pn = racemic propane-1,2-diamine) with Na2[Fe(CN)5NO]·2H2O in aqueous solution and has been charaterised by IR and Mössbauer spectroscopy and magnetic studies. Single crystal structure analysis revealed octahedrally coordinate cations [Ni(pn)3]2+ and anions [Fe(CN)5NO]2−.

Single Crystal Structure Analysis

Single crystals as well as microcrystalline powders of Cs2NiO2 were obtained via the azide/nitrate route from appropriate mixtures of CsN3, CsNO3 and NiO. The single-crystal structure analysis confirmed that Cs2NiO2 crystallizes in the tetragonal space group I4/mmm (Z = 2, a = 4.4090(3), c = 13.576(3) Å , R1 = 0.036, wR2 = 0.093). Above 45 K, Cs2NiO2 is paramagnetic, and an analysis based on the Curie-Weiss law has resulted in μ = 2.89 μB paramagnetic units, θ = −30.8 K and TN ∼ 20 K.

The arrangement of hydroxyl groups in the benzene ring has a significant effect on the propensity of dihydroxybenzoic acids (diOHBAs) to form different solid phases when crystallized from solution. All six diOHBAs were categorized into distinctive groups according to the solid phases obtained when crystallized from selected solvents. A combined study using crystal structure and molecule electrostatic potential surface analysis, as well as an exploration of molecular association in solution using spectroscopic methods and molecular dynamics simulations were used to determine the possible mechanism of how the location of the phenolic hydroxyl groups affect the diversity of solid phases formed by the diOHBAs. The crystal structure analysis showed that classical carboxylic acid homodimers and ring-like hydrogen bond motifs consisting of six diOHBA molecules are prominently present in almost all analyzed crystal structures. Both experimental spectroscopic investigations and molecular dynamics simulations indicated that the extent of intramolecular bonding between carboxyl and hydroxyl groups in solution has the most significant impact on the solid phases formed by the diOHBAs. Additionally, the extent of hydrogen bonding with solvent molecules and the mean lifetime of solute–solvent associates formed by diOHBAs and 2-propanol were also investigated.
