Crystal structure and Hirshfeld surface analysis of di­aqua­bis­(N,N-di­ethyl­nicotinamide-κN1)bis­(2,4,6-tri­methyl­benzoato-κO)manganese(II)

The MnII complex is centrosymmetric and the molecules are linked by O—H⋯O and C—H⋯O hydrogen bonds into the three-dimensional supramolecular network.

Crystal structure of trans-di­aqua­bis­(4-cyano­benzoato-κO)bis­(nicotinamide-κN1)cobalt(II)

In the title complex, the CoII atom is located on an inversion centre and is coordinated by two 4-cyanobenzoate (CNB) anions, two nicotinamide (NA) ligands and two water molecules. The four O atoms in the equatorial plane form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination sphere is completed by the two N atoms of the NA ligands in the axial positions.

Crystal structure and Hirshfeld surface analysis of aqua­bis­(nicotinamide-κN)bis­(4-sulfamoylbenzoato-κO1)copper(II)

The CuII cation, located on a twofold rotation axis, is coordinated by two 4-sulfamoylbenzoate anions, two nicotinamide (NA) molecules and one water molecule in a slightly distorted square-pyramidal geometry.

Crystal structure and Hirshfeld surface analysis of hexa­kis­(μ-benzoato-κ2O:O′)bis­(pyridine-3-carbo­nitrile-κN1)trizinc(II)

The asymmetric unit of the title complex contains one half of the complex molecule, one and a half ZnII cations, three benzoate (Bnz) and one pyridine-3-carbonitrile (CPy) molecule; the Bnz anions act as bidentate ligands through the carboxylate O atoms, while the Cpy anion acts as a monodentate N(pyridine)-bonding ligand. The complete centrosymmetric trinuclear complex thus comprises a linear array of three ZnII cations. In the crystal, the Bnz anions link to the Cpy N atoms via weak C—H⋯N hydrogen bonds, forming a two-dimensional network. The Hirshfeld surface analysis confirms the role of H-atom contacts in establishing the packing.

Crystal structure of catena-poly[[[di­aqua­bis­(2,4,6-tri­methyl­benzoato-κO)cobalt(II)]-μ-aqua-κ2O:O] dihydrate]

In {[Co(C10H11O2)2(H2O)3]·2H2O}n, the CoII atom is coordinated by two TMB anions and two water molecules in the basal plane, while another water molecule bridges the CoII atoms in the apical directions, forming polymeric chains running along [001].

Crystal structure of bis­(μ-3-nitro­benzoato)-κ3O,O′:O;κ3O:O,O′-bis­[bis­(3-cyano­pyridine-κN1)(3-nitro­benzoato-κ2O,O′)cadmium]

In the title cadmium complex of 3-nitrobenzoate and 3-cyanopyridine, binuclear centrosymmetric molecules are present, with cadmium being surrounded in an N2O5 coordinaton set in a distorted pentagonal–bipyramidal shape.

Crystal structure and Hirshfeld surface analysis of aqua­bis­(nicotinamide-κN1)bis­(2,4,6-tri­methyl­benzoato-κO)zinc

In the title Zn complex, the ZnII cation is five-coordinated in a distorted trigonal–bipyramidal geometry. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (58.4%), H⋯C/C⋯H (20.3%) and H⋯O/O⋯H (18.3%) interactions.

Crystal structure and Hirshfeld surface analysis of di­aqua­bis­(isonicotinamide-κN)bis­(2,4,6-tri­methyl­benzoato-κO1)nickel(II) dihydrate

In the title NiII complex, the divalent Ni ion occupies a crystallographically imposed centre of symmetry and is coordinated by two O atoms from the carboxylate groups of two 2,4,6-trimethylbenzoate ligands, two N atoms from the pyridyl groups of two isonicotinamide ligands and two water molecules in a slightly distorted octahedral geometry. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from H⋯H (59.8%), O⋯H/H⋯O (20.2%) and C⋯H/H⋯C (13.7%) interactions.

Crystal structure of catena-poly[[aqua­bis­(4-cyano­benzoato-κO)copper(II)]-μ-N,N-di­ethyl­nicotinamide-κ2N1:O]

The asymmetric unit of the title polymeric compound contains one CuII atom, one coordinating water molecule, two 4-cyanobenzoate (CB) ligands and one coordinating N,N-diethylnicotinamide (DENA) molecule. The DENA ligands bridge adjacent Cu2+ ions, forming polymeric coordination chains running along the b axis.

Crystal structure of di­aqua­bis­(4-tert-butyl­benzoato-κO)bis­(nicotinamide-κN1)cobalt(II) dihydrate

The asymmetric unit of the monomeric cobalt complex, [Co(C11H13O2)2(C6H6N2O)2(H2O)2]·2H2O, contains one half of the complex molecule, one coordinating and one non-coordinating water, one 4-tert-butylbenzoate (TBB) ligand and one nicotinamide (NA) ligand; the Co atom lies on an inversion centre. The coordinating water molecules are hydrogen bonded to the carboxyl O atoms [O ⋯ O = 2.6230 (17) Å], enclosing an S(6) hydrogen-bonding motif, while intermolecular O—H⋯O hydrogen bonds link two of the non-coordinating water molecules to the coordinating water molecules and NA anions. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the molecules, enclosing (8), (10) and (12) ring motifs, forming layers parallel to (001).
