چکیده
The asymmetric unit of the title compound, [Na(2)(C(8)H(8)O(8))](n), contains one Na(+) ion and half of a 2,3-bis(carboxymethyl)butanedioate (H(2)BTC(2-)) dianion, which lies on a center of symmetry. The dianion exhibits a μ(10)-bridging mode. Each Na atom lies in a NaO(6) octa-hedron defined by six O atoms from five dianions. Adjacent NaO(6) octa-hedra share a common O-O edge, generating a biocta-hedron; adjacent biocta-hedra are O-O edge-connected to one another, building up a chain along [001]. The chains are connected by adjacent H(2)BTC(2-) anions into a three-dimensional framework. The structure is further stabilized by O-H⋯O hydrogen bonds.

ABSTRACT An earlier developed alkylating path leading to tetraalkylated diaminomaleonitrile derivatives was explored. Attempts to explain the reactivity of the representative dialkylated diaminomaleonitrile 2,3-bis[(3-pyridylmethyl)amino]-2(Z)-butene-1,4-dinitrile during the alkylation reaction were performed using X-ray and density functional theory (DFT) studies. The condensed Fukui functions...

In the title complex, {[Cd(C(9)H(8)NO(4))(2)(H(2)O)(2)]·4H(2)O}(n), the Cd(II) atom (site symmetry 2) is coordinated by six O atoms from four crystallographically related 1-(1,2-dicarboxyl-ate)pyridin-1-ium ligands (L) and from two water molecules in a distorted octahedral geometry. Paired L ligands connect Cd(II) atoms into a chain motif parallel to [001], which is further inter-linked by O-H⋯...
متن کاملPhase transfer catalyzed reaction of disodium salt of 1,3-dihydroxybenzene with propargyl bromide in solid-liquid biphasic condition
The present work describes, the reaction between disodium salt of 1,3-dihydroxybenzene (in situ formation) and propargyl bromide was carried out in a solid-liquid biphasic phase transfer catalytic system at 50°C. Higher selectivity of the bis-derivative (1,3-bis(prop-2-ynyloxy)benzene) was obtained under solid-liquid PTC condion. The conversion of propargyl bromide of more than 99% was achieved...
