The title compound contains five-coordinate ZnII ions intermediate between square-pyramidal and trigonal–bipyramidal coordination geometries. The ZnII ions are connected by 2-carboxycinnamate (cca) ligands and N,N′-bis-(pyridine-4-carboxamido)piperazine (4-pcap) ligands to construct a non-interpenetrated, tri-periodic coordination polymer with embedded [Zn2(OCO)2] dimeric units. Treating these as six-connected nodes reveals an overall (41263) pcu topology.
data reports (HM)Tetrakis(μ-acetato-κ2O:O′)bis[(tetrahydrofuran-κO)chromium(II)]
Centrosymmetric [Cr2(OAc)4(THF)2] consists of two CrII atoms that are bridged by four acetate ions to yield a typical paddle-wheel structure. Furthermore, each chromium atom bears an axially bound THF ligand to give a square-pyramidal coordination.
data reports (HM)Poly[diaqua[μ-1,4-bis(pyridin-4-ylmethyl)piperazine][μ-4-(carboxylatoethyl)benzoato]nickel(II)]
The divalent nickel compound {[Ni(ceb)(bpmp)(H2O)2]n, (ceb is (4-(carboxyethyl)benzoate; bpmp is 1,4-bis(pyridin-4-ylmethyl)piperazine) crystallizes as a fivefold interpenetrated tri-periodic coordination polymer without co-crystallized species.
