Di-aqua-{2,2'-dimeth-oxy-6,6'-[(1E,1'E)-propane-1,3-diylbis(aza-nylyl-idene)bis-(methanylyl-idene)]diphenolato}nickel(II).

ABSTRACT: In the mol-ecule of the title compound, [Ni(C19H20N2O4)(H2O)2], the central Ni(II) ion lies on a mirror plane and is surrounded by an N2O4 coordination set in the form of a distorted octa-hedron defined by the O atoms of two water mol-ecules and by two phenolic O and two imine N atoms of the tetra-dentate Schiff base ligand. In the crystal, O-H?O hydrogen bonds between the water mol-ecules and the phenolic and meth-oxy O atoms of neighbouring mol-ecules lead to the formation of rods propagating parallel to [100].

Crystal structure of di-?-acetato-di-acetatobis-(?-6,6'-dimeth-oxy-2,2'-{[(propane-1,3-diylbis(aza-nylyl-idene)]bis-(methanylyl-idene)}diphenolato)tetra-zinc.

Project description:The tetra-nuclear title complex, [Zn4(C19H20N2O4)2(CH3COO)4], is formed from two dinuclear motifs related by an inversion centre. The two crystallographically independent Zn(II) ions in the asymmetric unit are in different coordination environments. One is square-based pyramidal with one O atom of an acetate group occupying the axial position and two N and O atoms of one bmspd [H2bmspd = N,N'-bis-(3-meth-oxy-salicyl-idene)propyl-ene-1,3-di-amine] Schiff base ligand forming the basal plane. The other Zn(II) atom is six-coordinated by four O atoms of the bmspd ligand forming the equatoral plane and two O atoms of different acetate groups located in the axial positions. As a result, the two phenolic planes of the bicompartmental Schiff base ligand are distorted slightly. However, the planes of the two Schiff base ligands are parallel. In addition, the Zn-N and Zn-O bond lengths span the reasonable ranges 2.062?(2)-2.073?(2) and 1.9261?(15)-2.4356?(16)?Å, respectively. The Zn?Zn distances separated by phenolic O atoms are 3.2466?(4)?Å while the Zn?Zn distances bridged by acetate groups are 5.9835?(6)?Å. The tetra-nuclear moieties are connected by van der Waals interactions, and form a chain along c axis.

{4,4',6,6'-Tetrachloro-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphenolato}dioxidomolyb-denum(VI).

Project description:The asymmetric unit of the title compound, [Mo(C(19)H(16)Cl(4)N(2)O(2))O(2)], comprises two independent mol-ecules (A and B). The geometry around the Mo(VI) atom is distorted octa-hedral in each complex mol-ecule, supported by two oxide O atoms and the N(2)O(2) donor atoms of the coordinating ligand. The dihedral angle between the benzene rings is 74.96?(11)?Å for mol-ecule A and 76.05?(11)?Å for mol-ecule B. In the crystal, the B mol-ecules are linked by pairs of C-H?Cl hydrogen bonds, forming inversion dimers. The crystal structure is further stabilized by C-H?? inter-actions. An inter-esting feature of the crystal structure is a Cl?Cl contact [3.3748?(18)?Å], which is shorter than the sum of the van der Waals radii of Cl atoms (3.50?Å).
