A nickel(II) coordination complex, bis[2,6-bis(1H-benzimidazol-2-yl-κN3)pyridine-κN]nickel(II) sulfate, [Ni(C19H13N5)2]SO4or [Ni(H2L)2]SO4, having four peripheral tetrahedrally oriented N—H donor units, combines with sulfate bridges to create hydrogen-bonded structures of varied dimensionality. The three crystal structures reported herein in the space groupsP212121,I\overline{4} andPccnare defined solely by strong charge-assisted N—H...O hydrogen bonds and contain disordered guests (water and dimethylformamide) that vary in size, shape and degree of hydrophilicity. Two of the compounds are channelled solids with three-dimensional structures, while the third is one-dimensional in nature. In spite of their differences, all three present a striking resemblance to the previously reported anhydrous relative [Guoet al.(2011).Chin. J. Inorg. Chem.27, 1517–1520], which is considered as the reference framework from which all three title compounds are derived. The hydrogen-bonded frameworks are described and compared using crystallographic and topological approaches.

AbstractThe investigation of the crystal structures of three closely related sulfonamides, namely N-(2-fluorobenzoyl)-2-methylbenzenesulfonamide (I), N-(2-fluorobenzoyl)-4-methylbenzenesulfonamide (II) and N-(2-fluorobenzoyl)-2-chlorobenzenesulfonamide (III) by analysing intermolecular interactions and the packing patterns, and also by Hirshfeld surface analyses is presented. Compound (I) has a three-dimensional (3D) network, in which N–H···O and C–H···F chains build up two-dimensional (2D) arrays, which are extended into a 3D network through C–H···π interactions. In (II), alternating N–H···O and C–H···O rings form one-dimensional (1D) ribbons, which are interconnected by C–H···π interactions to build a 2D network. In (III), 2D sheets comprising N–H···O rings, C–H···π chains, Cl···F and F···F contacts are stacked by π···π interactions to form a 3D network. Hirshfeld surface analyses, comprising d

Herein, we describe the preparation of heteronuclear dirhodium-silver complexes by reaction between molecular Rh(II)-Rh(II) compounds [Rh2(μ-O2CR)4L2] (R = Me, Ph (1), CH2OEt (2); L = solvent molecules) with paddlewheel structure and PPh4[Ag(CN)2]. One-dimensional coordination polymers of (PPh4)n[Rh2(μ-O2CR)4Ag(CN)2]n (R = Me (3), Ph (4), CH2OEt (5)) formula have been obtained by replacement of the two labile molecules in the axial positions of the paddlewheel structures by a [Ag(CN)2]− bridging unit. The crystal structures of 3–5 display a similar arrangement, having anionic chains with a wavy structure and bulky (PPh4)+ cations placed between the chains. The presence of the (PPh4)+ cations hinders the existence of intermolecular Ag-Ag interactions although several C-H····π interactions have been observed. A similar reaction between [Rh2(μ-O2CCMe3)4(HO2CCMe3)2] and PPh4[Ag(CN)2] led to the molecular compound (PPh4)2{Rh2(μ-O2CCMe3)4[Ag(CN)2]2} (6) by replacement of the axial HO2CCMe3 ligands by two [Ag(CN)2]− units. The trimethylacetate ligand increases the solubility of the complex during the crystallization favouring the formation of discrete heteronuclear species.
