The title complex {[Ph2P(tBuN)2](Cl)Si:->Fe(CO)4} (2) was synthesized via the reaction of chlorosilylene [Ph2P(tBuN)2]SiCl (1), supported by an iminophosphonamide ligand with Fe(CO)5 in THF. molecular structure 2 fully characterized NMR (1H, 13C, 29Si, and 31P) IR spectroscopies, as well single-crystal X-ray diffraction (SCXRD) analysis. In SCXRD analysis 2, silylene located axial positions ...

Regionalised activation of canonical Wnt signalling via beta-catenin stabilisation is a key early step in embryonic patterning in many metazoans, including the basally diverging cnidarians, but the upstream maternal cues appear surprisingly variable. In Clytia, regionalised beta-catenin stabilisation defining a presumptive 'oral' territory is determined by two maternally coded Frizzled family W...

The title Co(II) complex, [Co(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], contains two 4-dimethyl-amino-benzoate (DMAB) anions, one isonicotinamide (INA) ligand and two coordinated water mol-ecules. One of the DMAB anions acts as a bidentate ligand, while the other is monodentate. The four O atoms in the equatorial plane around the Co atom form a highly distorted square-planar arrangement, wh...

The title compound, [Fe(CF(3)O(3)S)(C(36)H(44)N(4))], is an iron(III) porphyrin complex with the trifluoro-methane-sulfonate anion as an axial ligand. The Fe atom is displaced by 0.219 (2) Å toward the trifluoro-methane-sulfonate anion from the 24-atom mean plane of the porphyrin, resulting in a distorted FeN(4)O square-based pyramidal geometry. One ethyl-ene group is disordered over two orient...

In the title complex, [CaI(C(4)H(10)O(2))(3)]I, the Ca(II) atom is seven-coordinated by six O atoms from three 1,2-dimeth-oxy-ethane (DME) ligands and one iodide anion in a distorted penta-gonal-bipyramidal geometry. The I atom and one of the O atoms from a DME ligand lie in the axial positions while the other O atoms lie in the basal plane. The other iodide anion is outside the complex cation.

In the title compound, [Sn(CH3)3(C7H7N2O2S)(H2O)], the Sn(IV) atom has a distorted trigonal-bipyramidal coordination geometry, with one carboxyl-ate O atom of the 2-(4-methyl-pyrimidine-2-sulfan-yl)acetate ligand and the O atom of a water mol-ecule in axial positions, and three methyl groups in equatorial positions. In the crystal, mol-ecules are linked via O-H⋯O and O-H⋯N hydrogen bonds, formi...
