چکیده
The asymmetric unit of the title coordination polymer, {[Mn(C(6)Cl(2)O(4))(C(10)H(8)N(2))]·2C(2)H(5)OH}(n), consists of one Mn(II) ion, one 2,2'-bipyridine (bpy) ligand, one chloranilate (CA(2-)) ligand and two ethanol solvent mol-ecules. The Mn(II) ion is octa-hedrally coordinated by two N atoms of one bpy ligand and four O atoms of two chloranilate ions. The chloranilate ion serves as a bridging ligand between the Mn(II) ions, leading to an infinite zigzag chain along [101]. π-π stacking inter-actions [centroid-centroid distance = 4.098 (2) Å] is observed between the pyridine rings of adjacent chains. The ethanol mol-ecules act as accepters as well as donors for O-H⋯O hydrogen bonds, and form a hydrogen-bonded chain along the a axis. The H atoms of the hy-droxy groups of the two independent ethanol mol-ecules are each disordered over two sites with equal occupancies.

In the title coordination polymer, [Mn(C6Cl2O4)(C2H5OH)2] n , the Mn(II) atom and the chloranilate [systematic name: 2,5-di-chloro-3,6-dioxo-cyclo-hexa-1,4-diene-1,4-bis-(olate)] ion lie on crystallographic inversion centers. The geometry around the Mn(II) atom is a distorted octa-hedron involving four O atoms of two chloranilate ions and two O atoms from two ethanol mol-ecules. The chloranilat...

In the title compound, [Cd(2)(C(6)H(8)O(4))(2)(C(16)H(20)N(4))(H(2)O)(4)](n), penta-gonal-bipyramidally coordinated Cd(II) ions are connected into {Cd(2)(2,2-dimethyl-succinate)(2)(H(2)O)(4)} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands into [Cd(2)(2,2-dimethyl-succinate)(2)(3-bpmp)(H(2)O)(4)](n) coordina...

The title compound, [Ni(C(2)O(4))(C(10)H(8)N(2))](n), is isostructural with its Mn(II), Fe(II), Cu(II) and Zn(II) analogues. Each Ni(II) atom is chelated by two oxalate ligands and one 2,2'-bipyridine, forming a slightly distorted octa-hedral geometry. Oxlate acts as a bridge to link neighbouring pairs of Ni(II) cations, forming a one-dimensional wave-like chain. The crystal showed partial inve...
