In the centrosymmetric title complex, [Co(C(7)H(4)NO(3)S)(2)(C(6)H(15)N(3))(2)], the Co(II) ion is coordinated by two saccharinate (sac) anions and two neutral 2-piperazin-1-ylethanamine (ppzea) ligands, showing a distorted octa-hedral coordination. Sac is O-bonded via the carbonyl group, while ppzea acts as an N,N'-bidentate chelating ligand. The mol-ecules are connected by N-H⋯N and N-H⋯O hydrogen bonds, forming a linear chain running parallel to the crystallographic a axis. The compound is isostructural with the reported Ni, Zn, and Cd analogues.

The manganese title complex, [Mn(CHNO)(CHNO)(HO)]·2HO, is one of the first 4-amino 3-nitro-benzoic acid (4 A3NBA) monoligand metal complexes to be synthesized. It crystallizes in the centrosymmetric monoclinic space group 2/ with the complex mol-ecules located on inversion centers. Four 4 A3NBA ligand mol-ecules are monodentately coordinated by the Mn ion through the carb-oxy-lic oxygen atoms while the other two positions of the inner coordination sphere are occupied by water mol-ecules, giving rise to a distorted octa-hedron, and two water mol-ecules are in the outer coordination sphere.

The reaction between the (,)-fixolide 4-methyl-thio-semicarbazone and Pd chloride yielded the title compound, [Pd(CHNS)]·CHO {common name: -bis-[(,)-fixolide 4-methyl-thio-semicarbazonato-κ ]palladium(II) ethanol monosolvate}. The asymmetric unit of the title compound consists of one bis-thio-semicarbazonato Pd complex and one ethanol solvent mol-ecule. The thio-semicarbazononato ligands act as metal chelators with a configuration in a distorted square-planar geometry.

In the structure of the title solvated complex, [Pt(CHNS)(CHN)]·CHOS or -[Pt(4-)(qdt)]·dmso (4- = 4-amino-pyridyl, CHN; qdt = quinoxaline-2,3-di-thiol-ate, CHNS; dmso = dimethyl sulfoxide, CHOS) the centrosymmetric complex exhibits Pt-S distances in agreement with other Pt-S bond lengths found in platinum(IV) di-thiol-ene complexes. The qdt ligands have inter-molecular inter-actions with an amine hydrogen atom on a 4- ligand (hydrogen bonding) and have sandwich π-π inter-actions with a neighboring qdt ligand.

The reaction cavities of the nitro groups in the crystals of the title compounds, -[Co(NO)(NCS)(CHN)]·, = SCN (I), Cl·HO (II), and (ClO )(SCN) (III), have been investigated, revealing that the geometry of the inter-molecular N-H⋯O hydrogen bonds in (I) is unsuitable for nitro-nitrito photo-isomerization. The common main building block of these crystal structures is a centrosymmetric pair of complex cations connected by pairwise N-H⋯O(nitro) hydrogen bonds forming an (4) ring, which is a narrow diamond shape in (I) but is approximately square in (II) and (III). The structure of (I) was reported earlier [Börtin (1976 ▸).

Structural characterization of the ionic complexes [FeCl(CHP)][FeCl]·0.59CHCl or [(dppen)FeCl][FeCl]·0.59CHCl (dppen = -1,2-bis-(di-phenyl-phosphane)ethyl-ene, PCH) and [FeCl(CHP)][FeCl]·CHCl or [(dpbz)FeCl][FeCl]·CHCl (dpbz = 1,2-bis-(di-phenyl-phosphane)benzene, PCH) demonstrates coordination of two bidentate phosphane ligands (bis-phosphanes) to a single iron(III) center, resulting in six-coordinate cationic complexes that are balanced in charge by tetra-chlorido-ferrate(III) monoanions.
