The crystal structure of zinc acetate dihydrate, Zn(CH3COO)2.2H2O

The crystal structure of cobalt(II) bisacetylacetone dihydrate

“…It would be interesting to test these deductions by comparing the bond-lengths in similar compounds of cobalt and other transition metals, but there are few reports of sufficiently accurate structure determinations. For cobalt acetate tetrahydrate, van Niekerk & Schoening (1953) find two Co-O bonds of length 2.12 l and four Co-H20 bonds, two of which are 2.06 A long and the other two 2.11 A long, but these values are obtained from a study of nickel acetate tetrahydrate with which the cobalt compound is isomorphous. The similarity of these bond lengths may not be significant.…”

Directed anisotropy in bis(acetato-κ2O,O′)diaquazinc(II) at 110 and 250 K

“…This hydrogen bonding results in an infinite two-dimensional network in the crystallographic bc plane. Between the planes no strong interactions can be detected (van Niekerk et al, 1953). The hydrogenbonded sheet-like structure is also reflected in the morphology of the crystals, which are shaped as plates where the form {100} has the smallest dimension.…”

“…The room-temperature structure of the title compound, (I), is known from the literature (van Niekerk et al, 1953;Semenenko & Kurdyumov, 1958;Kaduk & Chen, 1996;Ishioka et al, 1997) to form a two-dimensional network by hydrogen bonding, with only very weak interactions in the third direction. The displacement ellipsoids show a large anisotropy and the Zn-O2 bond (Ishioka et al, 1997) fails the Hirshfeld rigid-bond test (Hirshfeld, 1976) by 11 , as calculated using PLATON (Spek, 2003).…”

The crystal structure of zinc salicylate dihydrate

“…Merritt, Cady & Mundy (1954) found two Zn-O distances of 2.05 and 2.27 J~ and two Zn-N distances of 2.06/~ in zinc 8-hydroxyquinolate dihydrate. Finally, in zinc acetate dihydrate distances of 2.14, 2.17, and 2.18 • were found in the badly distorted Zn-O octahedron ( van Niekerk, Schoening & Talbot, 1953).…”
