Crystallization experiments with the dinuclear chelate ring complex di-μ-chlorido-bis­[(η2-2-allyl-4-meth­oxy-5-{[(propan-2-yl­oxy)carbon­yl]meth­oxy}phenyl-κC1)platinum(II)]

Crystallization experiments with the dinuclear chelate ring complex di-μ-chlorido-bis­[(η2-2-allyl-4-meth­oxy-5-{[(propan-2-yl­oxy)carbon­yl]meth­oxy}phenyl-κC1)platinum(II)] using five different conditions has resulted in four different complexes.

Acetic anhydride at 100 K: the first crystal structure determination

Acetic anhydride is a widely used acetyl­ation reagent in organic synthesis. The crystal and mol­ecular structure, as determined by single-crystal X-ray analysis at 100 K, is reported for the first time. The mol­ecule adopts an exact C2-symmetric conformation about a crystallographic twofold axis.

A new synthetic route to the electron-deficient ligand tris­(3,4,5-tri­bromo­pyrazol-1-yl)phosphine oxide

A new procedure for the synthesis of the electron-poor ligand tris­(3,4,5-tri­bromo­pyrazol-1-yl)phosphine oxide is described. The structure displays a network of halogen bonds in the solid state.

New homodinuclear tris­(3-alkyl­pyrazol­yl)borate complexes of CoII and NiII with a tetra­acetyl­ethane dianion as a bridging ligand

Two new homodinuclear tris­(3-alkyl­pyrazol­yl)borate complexes of CoII and NiII with a tetra­acetyl­ethane dianion as the bridging ligand were synthesized and characterized by mass spectrometry and X-ray crystallography. A significant deviation from orthogonality between the acetyl­acetonate planes was observed in the two complexes.

A pseudo­tetra­hedral nickel(II) complex with a tridentate oxazoline-based scorpionate ligand: chlorido­[tris­(4,4-di­methyl­oxazolin-2-yl)phenyl­borato]nickel(II)

Three N atoms from the facially capping tridentate chelating tris­(4,4-di­methyl­oxazolin-2-yl)phenyl­borate ligand and a chloride ligand coordinate an NiII ion in a highly distorted tetra­hedral geometry. The Ni—Cl bond length [2.1851 (5) Å] is comparable to those found in a previously reported tris­(3,5-di­methyl­pyrazol-1-yl)hydro­borate derivative [2.1955 (18) and 2.150 (2) Å]. The mol­ecular structure deviates from C3v symmetry due to the structural flexibility of the tris­(4,4-di­methyl­oxazolin-2-yl)phenyl­borate ligand.

Silver(I) and rhenium(I) metal complexes of a 2,2′-bi­pyridine-functionalized third-generation tris­(pyrazol­yl)methane ligand

The heteroditopic Bipy–CH2–O–CH2–C(pz)3 ligand (Bipy-L; Bipy is 2,2′-bi­pyridine and pz is pyrazol­yl) reacts with AgI and ReI metallic centers to yield the {[Ag(μ-Bipy-L)]BF4·0.5Et2O}n coordination polymer and the [ReBr(Bipy-L)(CO)3] monometallic compound.

FcTp(R) (R = iPr or tBu): third-generation ferrocenyl scorpionates

Thallium(I) and cobalt(II) halide complexes of the ferrocenyltris(3-R-pyrazol­yl)borate ligand (FcTpR, with R = iPr or tBu) have been synthesized and their structural characteristics determined to expand the range of redox-active third-generation scorpionates.

Structure and physicochemical characterization of a naproxen–picolinamide cocrystal

The crystal structure is reported of a new 1:1 cocrystal of naproxen with picolinamide, and the pharmaceutically relevant properties are investigated. An NMR crystallography approach is used to distinguish between two crystallographically unique COOH–CONH hydrogen-bonded dimers and to confirm the location of the H atoms in the two dimers.

Accepted 15 July 2016

Side-on coordination mode of a pyrazolyl group in the structure of a divalent [Sm{B(3-Mepz)4}2] complex (3-Mepz is 3-methyl­pyrazol-1-yl)

Bis[tetra­kis­(3-methyl-1H-pyrazol-1-yl)borato]samarium(II) was synthesized by the reaction of SmI2 with potassium tetra­kis­(3-methyl­pyrazol­yl)borate in tetrahydrofuran. The X-ray structure analysis revealed an unusual side-on coordination mode of a 3-methyl­pyrazolyl group through an N=N group in the B(3-Mepz)4 ligand. The distortion is defined by the B—N—N—Sm torsion angle [85.5 (4)°].

Mono- and binuclear tris­(3-tert-butyl-2-sulfanyl­idene-1H-imidazol-1-yl)hydro­borate bis­muth(III) dichloride complexes: a soft scorpionate ligand can coordinate to p-block elements

The structure of a new mononuclear bis­muth(III) complex with the soft scorpionate ­(3-tert-butyl-2-sulfanyl­idene-1H-imidazol-1-yl)hydro­borate ligand is compared with that of the binuclear derivative.

Mol­ecular structures of tris­(1-tert-butyl-2-mercapto­imidazol­yl)hydro­borate complexes of titanium, zirconium and hafnium

The structural characterization of the tris(1-tert-butyl-2-mercaptoimidazol­yl)hydro­borate, [TmBut], complexes Cp[κ3S2,H-TmBut]MCl2 (M = Zr and Ti) by X-ray diffraction demonstrates that the [TmBut] ligand coordinates in a κ3S2,H mode, while the benzyl compounds [TmBut]M(CH2Ph)3 (M = Zr and Hf) exhibit κ3S3 coordination.
