In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu2+ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N—O groups of twoN-nitroso-N-pentylhydroxylaminate ligands [Cu—O = 1.9042 (17) and 1.9095 (16) Å]. The hydroxylaminate monoanions are bidentate chelating ligands. The Cu2+cations form stacks along [010], with intermolecular Cu...N contacts of 3.146 (2) and 3.653 (2) Å.

The reaction of O,O′-diisopropyl phosphorisothiocyanatidate, (iPrO)2P(O)NCS, with diethyl-(4-aminobenzyl)phosphonate leads to the new N-phosphorylated thiourea derivative, 4-[(EtO)2P(O)CH2]-C6H4NHC(S)NHP(O)(OiPr)2 (HL). The reaction of its potassium salt KL with Zn(II) or Co(II) in aqueous EtOH leads to the complexes of formulae M(L-O,S)2 (ZnL2, CoL2). The metal cation in all complexes is coordinated by two deprotonated ligands through the sulfur atoms of the thiocarbonyl groups and the oxygen atoms of the phosphoryl groups. The reaction of KL with Ni(II) leads to the formation of two types of complexes: the blue Ni(L-N,S)2 complex, where the ligand is coordinated through the nitrogen atom of the phosphorylamide group and the sulfur atom of the thiocarbonyl groups and light red Ni(L-O,S)2 complex with the same coordination of L– anion as it was observed for ZnL2 and CoL2. According to UV/Vis spectral data, it was established that the metal cation of Ni(L-N,S)2 is in a square-planar environment in CH2Cl2, whereas the Ni(L-O,S)2 complex shows features of tetrahedral complexes.

The title compound, [Pd(C3H5)(C17H15N3S2)]PF6, is built up by a [(η3-allyl)Pd]2+fragment coordinated by a 2,6-bis[(pyridin-2-yl)sulfanylmethyl]pyridine ligand coordinated through the N atoms. One of the S atoms is at a close distance to the metal centeratom [3.2930 (8) Å]. The PdIIatom is tetracoordinated in a strongly distorted square-planar environment mainly determined by the η3-allyl anion in which the central C atom is disordered over two equally occupied positions. The crystal packing is very compact and is characterized by a three-dimensional network of C—H...F interactions between the F atoms of each anion and several H atoms of the surrounding cationic complexes.

The synthesis and properties of the red dimeric nickel(11) complex [Ni2(C7H,N2)4], where C7H5N2-is the anion of 7-azaindole (1H-pyrrolo[2,3-b]pyridine), are reported. The diamagnetism and electronic spectrum are consistent with a square-planar environment about each nickel atom. Adimeric molecular structure with four anionic 7-azaindole ligands bridging a pair of bonded nickel atoms is proposed.

In the title complex, [Pt(NCS)2(C10H9N3)], the PtIIion is four-coordinated in a distorted square-planar environment by the two pyridine N atoms of the chelating di-2-pyridylamine (dpa) ligand and two mutuallycisS atoms from two linear thiocyanate anions. The dpa ligand is not planar, the dihedral angle between the pyridine rings being 30.8 (4)°. In the crystal, the complex molecules are stacked in columns along theaaxis and are connected by intermolecular N—H...N hydrogen bonds, forming supramolecular chains along thebaxis.

The title compound, an (N^C)-cyclometalated gold(III) diazide, namely, diazido[5-ethoxycarbonyl-2-(5-ethoxycarbonylpyridin-2-yl)phenyl-κ2 C 1,N]gold(III), [Au(C17H16NO4)(N3)2] or Au(ppyEt)(N3)2, was synthesized by reacting Au(ppyEt)Cl2 with NaN3 in water for 24 h. The complex has been structurally characterized and features a gold center with a square-planar environment. The Au—N(azide) bond lengths are significantly different depending on the influence of the atom trans to the azide group [Au—N(trans to C) of 2.067 (2) Å versus Au—N(trans to N) of 2.042 (2) Å]. The azide groups are twisted in-and-out of plane by 56.2 (2)°.

The title compound, [Fe2(C44H28N4O)2O], was obtained as a by-product during the synthesis of FeIII tetraphenylporphyrin perchlorate. It crystallizes as a new polymorphic modification in addition to the orthorhombic form previously reported [Hoffman et al. (1972). J. Am. Chem. Soc. 94, 3620–3626; Swepston & Ibers (1985) Acta Cryst. C41, 671–673; Kooijmann et al. (2007). Private Communication (refcode 667666). CCDC, Cambridge, England]. In its crystal structure, the two crystallographically independent FeIII cations are coordinated in a square-planar environment by the four N atoms of a tetraphenylporphyrin ligand. The FeIII-tetraphenylporphyrine units are linked by a μ2-oxido ligand into a dimer with an Fe—O—Fe angle close to linearity. The final coordination sphere for each FeIII atom is square-pyramidal with the μ2-oxido ligand in the apical position. The crystal under investigation consisted of two domains in a ratio of 0.691 (3): 0.309 (3).
