    Notes: Abstract The complex, [Zn(L)(NCO)]Cl · 3H2O (1) (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,01.18,07.12]docosane), has been synthesized and structurally characterized. 1 crystallizes in the monoclinic system, space group P21/n with a = 10.530(3), b = 9.315(2), c = 27.188(3) Å, β = 92.58(1)°, V = 2664.1(9)Å3, and Z = 4. The zinc atom is in a distorted squarepyramidal environment with the four nitrogen atoms of the macrocycle and one nitrogen atom of the isocyanate ligand.

    Notes: Abstract A novel compound catena-(μ-CrO4-O,O′)[Ni(L1)Ni(L2)] 3H2O (1) (L1 = 3,5,10,12-tetramethyl-1,4,8,11-tetraazacyclotetradecane and L2 = 2,5,9,12-tetramethyl-1,4,8,11-tetraazacyclotetradecane) has been synthesized for the first time and structurally characterized. 1 crystallizes in the triclinic space group Pī with a = 9.623(1), b = 10.084(1), c = 12.723 (3) Å, α = 66.74(2), β = 75.20(1), γ = 72.02(1)°, V = 1066.2(3) Å3, and Z = 2. The coordination environment around the Ni(II) ions is an axially elongated octahedron with the secondary amines of the isomeric ligands and two oxygen atoms of [CrO4]2−.

    The structure of bis[(o-hydroxyphenoxy)ethoxy]ethane monohydrate (1985)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 3 (1985), S. 21-26 
    Details
    ISSN: 1573-1111
    Keywords: Crystal structure ; (hydroxyphenoxy) ethoxy ethane hydrate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The title compound (C18H22O6·H2O) crystallizes in space groupP212121 witha=25.909(5),b=8.542(3),c=8.187(3) Å,Z=4. The structure was determined from 1538 X-ray diffractometer data and refined toR=8.05%. The polyether adopts an annular structure with the water molecule at the center, and is slightly folded like the wings of a butterfly. As usual, all torsion angles about C−O aretrans and about C−C aregauche. This complex displays 3 three-center (bifurcated) and 1 two-center hydrogen bonds, between phenolic hydroxyl and water oxygen. The latter is involved in an infinite homodromic chain O(1)−H...O W −H...O(1)−H...
