catena-Poly[sodium [[tris(3-methylpyridine-2-carboxylato)europate(III)]-μ-3-methylpyridine-2-carboxylato] trihydrate]
In the title structure, {Na[Eu(C(7)H(6)NO(2))(4)]·3H(2)O}(n), the Eu(III) atom is nine-coordin-ated within a slightly distorted tricapped trigonal-prismatic coordination geometry defined by five carboxyl-ate-O atoms and four pyridine-N atoms. One of the carboxyl-ate ligands bridges the Eu cations, forming a one-dimensional coordination polymer along the b axis. The Eu-O bond distances lie withi...

The polymeric structure of the title compound {[Li(C(6)H(3)N(2)O(4))(H(2)O)]·H(2)O}(n), contains two symmetry-independent Li(I) complex units, both having distorted trigonal-bipyramidal coordination environments. The Li(I) ions are bridged by both the N and O atoms of the ligands, generating two symmetry-independent polymeric chains propagating along the b-axis direction. In both ligands, the s...
متن کاملSynthesis of 5 - Methoxycarbonyl - 1 l - methylfuro ( 2 , 3 - c ) acridan - 6 ( 11 H ) ones
The plant family Rutaceae is known [1, 2] to be a prolific source of furoquinoline and pyranoquinoline alkaloids. Along with them acridine alka loids [3, 4] have also been isolated from several members of the same plant family. Recently furanfused acridine systems such as 1 l-methylfuro(2,3-c)acridan-6(l lH)one (1) have also been reported [5-7] to occur in some rutaceous plants. Typical exampl...
متن کامل(3R*)-Methyl 3-[(2S*)-4,6-dimethoxy-2-(4-methoxyphenyl)-3-oxo-2,3-dihydro-1-benzofuran-2-yl]-2-methoxycarbonyl-3-phenylpropionate
The title compound, C(29)H(28)O(9), was isolated from the reaction of 4,6-dimeth-oxy-2-(4-methoxy-phen-yl)-3-benzofuran and α-methoxy-carbonyl-cinnaminate. The two aromatic rings form a dihedral angle of 22.7 (1)°. One methoxy-carbonyl group is disordered between two orientations in a 0.612 (4):0.388 (4) ratio. The crystal structure exhibits no significantly short inter-molecular contacts.

Graphs and Digraphs: A graph G = (V,E) is a structure that represents a discrete set V objects, called vertices or nodes, and a set of pairwise relations E between these objects, called edges. Edges may be directed from one vertex to another or may be undirected. The term “graph” means an undirected graph, and directed graphs are often called digraphs (see Fig. 1). Graphs and digraphs provide a...
