1-{(Z)-1-(2,4-Dichloro­phen­yl)-1-[2-(4-methyl­phen­oxy)eth­oxy]prop-1-en-2-yl}-1H-imidazol-3-ium nitrate

In the title salt, C₂₁H₂₁Cl₂N₂O₂⁺·NO₃⁻, the imidazole ring makes dihedral angles of 43.39 (14) and 10.9 (2)° with the 4-methyl­phenyl and 2,4-dichloro­phenyl rings, respectively. The mol­ecule adopts a Z conformation about the C=C double bond, which links the imidazole ring to the 4-methyl­phen­oxy unit via an eth­oxy chain. In the crystal, cations and anions are linked into chains by N—H...O and C—H...O hydrogen bonds.

Bis[μ-4-(4-carb­oxy­phen­oxy)phthalato]bis­[triaqua­cobalt(II)]

The dinuclear title complex, [Co₂(C₁₅H₈O₇)₂(H₂O)₆], lies across an inversion center. The unique Co^II ion is coordinated in a slightly distorted octa­hedral coordination geometry by two O atoms from a chelating 4-(carb­oxy­phen­oxy)phthalate ligand, three water O atoms and a further O atom from a bridging carboxyl­ate group of a symmetry-related 4-(carb­oxy­phen­oxy)phthalate ligand. In the crystal, O—H...O hydrogen bonds link the mol­ecules into a three-dimensional network.

catena-Poly[(acetato­chloridozinc)-μ-1,1′-[1,4-phenyl­enebis(methyl­ene)]di-1H-imidazole]

The title compound, [Zn(CH₃CO₂)Cl(C₁₄H₁₄N₄)]_n, is a one-dimensional coordination polymer in which the Zn^II ion is tetrahedrally ­coordinated by two N atoms of a bridging 1,1′-[1,4-phenyl­enebis(methyl­ene)]di-1H-imidazole ligand, an acetate O atom and a Cl atom. The Cl atom, two acetate O atoms and two acetate C atoms are located on a mirror plane. The coordination of the diimidazole ligand to the Zn^II ion gives an infinite one-dimensional zigzag structure along the b-axis direction with the charge balanced by the chloride and acetate ions.

3,3′,5,5′-Tetra-tert-butyl-2′-hy­droxy-[1,1′-biphen­yl]-2-yl 4-methyl­benzene­sulfonate

In the title mol­ecule, C₃₇H₄₈O₄S, the benzene rings in the biphenyl fragment are inclined to each other at 61.1 (1)°. The hy­droxy group is involved in a weak intra­molecular O—H...O_sulfonate hydrogen bond. One tert-butyl group is disodered over two orientations in a 0.682 (17):0.318 (17) ratio. In the crystal, weak C—H...O hydrogen bonds link the mol­ecules into columns in direction [100].

(4-Meth­oxy­phen­yl)(4-propyl­cyclo­hex­yl)methanone

The asymmetric unit of the title compound, C₁₇H₂₄O₂, contains two independent mol­ecules with different conformations. The least-squares plane through the cyclohexane ring makes dihedral angles of 52.9 (5) and 81.4 (4)° with the benzene ring in the two molecules. The cyclo­hexane ring adopts a chair conformation in both mol­ecules. In the crystal, weak C—H...O hydrogen bonds link mol­ecules related by translation in [100] into two crystallographically independent chains.

Isopropyl 3-phenyl­isoxazole-5-carboxyl­ate

In the title compound, C₁₃H₁₃NO₃, the isoxazole ring is approximately coplanar with the phenyl ring, the dihedral angle between their planes being 7.37 (19)°. In the crystal, centrosymmetrically related mol­ecules are linked into dimers by pairs of C—H...O hydrogen bonds, generating a ring of graph-set motif R₂²(10).

2-Methyl-1,2,4-triazolo[4,3-a]pyridin-2-ium tetra­fluoroborate

In the title salt, C₇H₈N₃⁺·BF₄⁻, the 1,2,4-triazolo[4,3-a]pyridinium cation is planar [maximum deviation of 0.016 (2) Å for all non-H atoms]. The cation and anion constitute a tight ionic pair with an F...N [2.911 (4) Å] inter­molecular attractive inter­action. The ionic pairs form dimers via stacking inter­actions between inversion-related cations, the normal distance between the cation planes being 3.376 (5) Å. The dimers are packed in stacks along the a axis and linked via C—H...F hydrogen bond, forming a three-dimensional network.
