6,6′-Dimeth­oxy-2,2′-(2,2,4-trimethyl­imidazolidine-1,3-diyl­dimethyl­ene)diphenol

The molecules of (I) are linked by a pair of C—H hydrogen bonds (Fig. 2). Atom C19 in the molecule at (x, y, z) acts as a hydrogen-bond donor, via H19, to the C8–C13 aryl ring of the molecule at (1 x, 1 y, 1 z), generating a dimer. Neighbouring dimers are linked by pair of C—H O hydrogen bonds into a chain (Fig. 3 and Table 1). Atom C22 in the molecule at (x, y, z) acts as a hydrogen-bond donor, via H22B, to atom O4 in the molecule at (1 x, y, 2 z), generating a chain of R2(6) rings (Bernstein et al., 1995)

Aqua­(6-meth­oxy-2-{[3-(3-meth­oxy-2-oxidobenzyl­amino)propyl­amino]meth­yl}phenolato)ethano­lnickel(II) nitrate

The title compound, [Ni(C19H25N2O4)(C2H6O)(H2O)]NO3, assembles into centrosymmetric dinuclear complexes through a pair of strong O—H⋯O hydrogen bonds.

6,6′‐Dimeth­oxy‐2,2′‐(ethane‐1,2‐diyldiammoniodimethyl­ene)diphenol dinitrate

In the title compound, C18H26N2O42+·2NO3−, the ions are linked into two chains by C—H⋯O hydrogen bonds; these chains are linked into sheets parallel to (001). The asymmetric unit consists of one cation, two half-cations and four anions. Two of the cations have a centre of symmetry at the mid-point of the central C—C bond.

Bis(1‐naphthyl­acetato‐κ2O,O)(1,10‐phenanthroline‐κ2N,N)zinc(II)

In the crystal structure of the title compound, [Zn(C12H9O2)2(C12H8N2)], there are two molecules in the asymmetric unit. The molecules are linked into a sandwiched sheet by six C—H⋯O hydrogen bonds.
