Poly[[diaqua(μ2-5,5-dioxodibenzo[b,d]thiophene-3,7-dicarboxylato)(μ2-ethylene glycol)manganese(II)] dimethylacetamide solvate]

Zebrafish sperm cryopreservation with N,N-dimethylacetamide.

High fecundity, rapid generation time, and external development of optically clear embryos make the zebrafish (Danio rerio) a convenient vertebrate model for genetic, developmental, and disease studies. Efficient sperm cryopreservation enhances the zebrafish model system by optimizing productive use of facility space, extending the reproductive lifetime of males, providing an alternative to liv...

Structural effect of glyme-Li(+) salt solvate ionic liquids on the conformation of poly(ethylene oxide).

The conformation of 36 kDa polyethylene oxide (PEO) dissolved in three glyme-Li(+) solvate ionic liquids (SILs) has been investigated by small angle neutron scattering (SANS) and rheology as a function of concentration and compared to a previously studied SIL. The solvent quality of a SIL for PEO can be tuned by changing the glyme length and anion type. Thermogravimetric analysis (TGA) reveals ...

Cytenamide acetic acid solvate

IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND (SYSTEMATIC NAME: 5H-dibenzo[a,d]cyclo-hepta-triene-5-carboxamide ethanoic acid solvate), C(16)H(13)NO·C(2)H(4)O(2), the cytenamide and solvent mol-ecules form a hydrogen-bonded R(2) (2)(8) dimer motif, which is further connected to form a centrosymmetric double ring motif arrangement. The cycloheptene ring adopts a boat conformation and the dihedr...

Cytenamide trifluoro­acetic acid solvate

Cytenamide forms a 1:1 solvate with trifluoro-acetic acid (systematic name: 5H-dibenzo[a,d]cyclo-hepta-triene-5-carboxamide trifluoro-acetic acid solvate), C(16)H(13)NO·C(2)HF(3)O(2). The compound crystallizes with one mol-ecule of cytenamide and one of trifluoro-acetic acid in the asymmetric unit; these are linked by O-H⋯O and N-H⋯O hydrogen bonds to form an R(2) (2)(8) motif. The trifluoro-me...
