چکیده
In the title coordination polymer, {[Zn(C(9)H(7)NO(4))(C(10)H(14)N(4))]·2H(2)O}(n), the Zn(II) ion displays a distorted tetra-hedral geometry with two imidazole N atoms from two 1,1'-(butane-1,4-di-yl)bis-(imidazole) (bbi) ligands and two carboxyl-ate O atoms from two 2,6-dimethyl-pyridine-3,5-dicarboxyl-ate (dpdc) ligands. The bbi and dpdc ligands bridge the Zn(II) ions, forming layers parallel to (011). O-H⋯O and O-H⋯N hydrogen bonds and π-π inter-actions between the imidazole rings [centroid-centroid distance = 3.807 (5) Å] connect the layers. Two of the three uncoordinated water mol-ecules are disordered, each over two 0.25-occupancy positions.

In the title coordination polymer, [Zn(C(8)H(4)O(5))(C(14)H(22)N(4))](n), the Zn(II) cation is coordinated by an O(2)N(2) donor set in a distorted tetra-hedral geometry. The Zn(II) ions are linked by μ(2)-OH-bdc (OH-H(2)bdc = 5-hy-droxy-isophthalic acid) and bbie ligands [bbie = 2,2'-diethyl-1,1'-(butane-1,4-di-yl)diimidazole], forming a two-dimensional layer parallel to the ab plane. The layer...

In the title compound, {[Co(C(10)H(14)N(4))(2)(H(2)O)(2)](NO(3))(2)}(n), the Co(II) ion lies on an inversion center and is six-coordinated in an octa-hedral environment by four N atoms from four different 1,1'-butane-1,4-diyldiimidazole ligands and two O atoms from the two water mol-ecules. The Co(II) atoms are bridged by ligands, generating a two-dimensional (4,4)-network. Adjacent fishnet pla...
