چکیده
In the crystal structure of the title coordination polymer, {[Zn(2)(C(17)H(8)O(10))(C(3)H(7)NO)(2)]·C(3)H(7)NO}(n), the mol-ecular build-ing block (MBB), viz. {Zn(2)(CO(2))(4)(C(3)H(7)NO)(2)}, comprises two zinc atoms, each bridged by three carboxyl-ate groups. These two Zn atoms exhibit different coordination environments: a distorted coordination intermediate between trigonal-pyramidal, and square-pyramidal formed by the two coordinated dimethyl-formamide mol-ecules and three carboxylate groups, and a distorted tetra-hedral coordination defined by carboxy-late groups of which three are bidentate bridging and the fourth is a monodentate ligand. Thus, each ligand connects four MBBs, forming the three-dimensional polymer.

The title compound, [Zn(2)(CHO(2))(C(8)H(3)O(5))(C(3)H(7)NO)(2)](n), is a three-dimensional metal-organic framework, of which two independent Zn(II) atoms (denoted Zn1 and Zn2) are linked by both 4-oxidoisophthalate and formate bridging ligands. The 4-oxidoisophthalate ligands link two Zn1-type and three Zn2-type atoms, forming a corrugated sheet roughly parallel to the ac plane. The formate io...

The crystal structure of the polymeric title compound, {[HgCl(2)(C(18)H(18)N(4))]·C(3)H(7)NO}(n), features an N-heterocyclic ligand which links adjacent HgCl(2) units into a helical chain running along the b axis. The coordination geometry of the Hg(II) atom is a distorted tetra-hedron. The dimethyl-formamide mol-ecule is disordered over two positions in a 1:1 ratio, and is linked to the comple...
