A phytochemical investigation on the ethyl acetate soluble fraction of Lonicera quinquelocularis (whole plant) led to the first time isolation of one new phthalate; bis(7-acetoxy-2-ethyl-5-methylheptyl) phthalate (3) and two new benzoates; neopentyl-4-ethoxy-3, 5-bis (3-methyl-2-butenyl benzoate (4) and neopentyl-4-hydroxy-3, 5-bis (3-methyl-2-butenyl benzoate (5) along with two known compounds...

We have prepared a range of alkynyl benzoates in high yields and have investigated their reactivities with the strong Lewis acid B(C6F5)3. In such molecules both σ-activation of the carbonyl and π-activation of the alkyne are possible. In contrast to the reactivity of propargyl esters with B(C6F5)3 which proceed via 1,2-addition of the ester and B(C6F5)3 across the alkyne, the inclusion of an a...

A second monoclinic polymorph of methyl 4-hydroxy-benzoate, C(8)H(8)O(3), is reported. The unit-cell dimensions are different from those of the previously reported monoclinic form [Vujovic & Nassimbeni (2006 ▶). Cryst. Growth Des.6, 1595-1597]. The asymmetric unit contains three crystallographically independent mol-ecules, as observed in the previous form. The crystal structure is stabilized by...

The asymmetric unit of the title salt, C(6)H(8)N(+)·C(7)H(5)O(4) (-), contains two anilinium cations and two 3,4-dihy-droxy-benzoate anions. An intra-moleculer O-H⋯O hydrogen bond occurs in each anion. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the cations and anions into a three-dimensional array. The structure is further consolidated by weak C-H⋯O inter-actions.

In the title salt C6H14N2 (2+)·2C7H4ClO2 (-), two 3-chloro-benzoate (3CBA) anions are bridged by one diprotonated 1,4-di-aza-bicyclo-[2.2.2]octane-1,4-diium (H2DABCO(2+)) dication through N-H⋯O hydrogen bonds. In this way, a trimeric unit is generated, in which the mean planes of the two 3CBA anions are twisted with respect to each other by a dihedral angle of 59.87 (9)°. The trimeric units are...

The paddle-wheel-type centrosymmetric dinuclear title complex, [Zn(2)(C(7)H(5)O(2))(4)(C(12)H(10)N(2))(2)], contains four bridging benzoate groups and two terminal trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene (L) ligands. The inversion center is located between the two Zn(II) atoms. The octa-hedral coordination around the Zn(II) atom, with four O atoms in the equatorial plane, is completed by a...

The title compound, [Ag(C(7)H(4)ClO(2))(C(6)H(8)N(2))(2)], is a mononuclear silver(I) complex. The Ag(I) atom is three-coordinated by two pyridine N atoms from two 5-methyl-pyridin-2-ylamine ligands and by one O atom of a 4-chloro-benzoate ligand, forming a distorted T-shaped coordination. In the crystal structure, the mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming ...

The complete mol-ecule of the title compound, [Nd(2)(C(7)H(5)O(2))(6)(C(12)H(8)N(2))(2)], is generated by a crystallographic inversion center. The two Nd(III) ions are linked by four bridging benzoate ions, with an Nd⋯Nd separation of 4.0360 (2) Å. As well as the bridging ligands, each Nd(III) ion is coordinated by one N,N'-bidentate phenanthroline ligand and an O,O'-bidentate benzoate ion. The...

In the title compound, C(6)H(9)N(2) (+)·C(7)H(6)NO(2) (-), the H atom of the N-H group and an H atom of the 2-amino group from the cation are involved in inter-molecular N-H⋯O hydrogen bonds with the O atoms of the carboxyl-ate group of the anion, forming an R(2) (2)(8) ring motif. These ring motifs are, in turn, connected by further N-H⋯O hydrogen bonds, forming a two-dimensional network. The ...

In the title salt, C(5)H(8)N(3) (+)·C(7)H(4)NO(4) (-), the pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The protonated N atom and one of the two 2-amino groups are hydrogen bonded to the 4-nitro-benzoate anion through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The carboxyl-ate mean plane of the 4-nitro-benzoate anion is twisted by 3.77 (5)° from t...
