چکیده
The asymmetric unit of the title three-dimensional coordination polymer, [Mn2Br6(C11H28N2O2)] n , consists of one Mn(II) cation, half of a dicationic N,N'-bis-(2-hy-droxy-eth-yl)-N,N,N',N'-tetra-methyl-propane-1,3-diaminium ligand (L) (the other half being generated by a twofold rotation axis), and three bromide ions. The Mn(II) cation is coordinated by a single L ligand via the hy-droxy O atom and by five bromide ions, resulting in a distorted octa-hedral MnBr5O coordination geometry. Four of the bromide ions are bridging to two adjacent Mn(II) atoms, thereby forming polymeric chains along the a and b axes. The L units act as links between neighbouring Mn-(μ-Br)2-Mn chains, also forming a polymeric continuum along the c axis, which completes the formation of a three-dimensional network. Classical O-H⋯Br hydrogen bonds are present. The distance between adjacent Mn(II) atoms is 4.022 (1) Å.

The title tetra-nuclear Cu(II) complex, [Cu(4)(C(12)H(12)N(2)O(2))(4)(CH(3)O)(4)(ClO(4))(2)](ClO(4))(2), is located around an inversion center. Each Cu(II) atom is coordinated by two cis-O atoms from two bridging methano-late anions and two cis-N atoms from two bridging 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in the basal plane, and is further coordinated by one O atom of the b...

In the title coordination polymer, [CdBr(2)(C(12)H(12)N(2)O(2))](n), the Cd(II) ion, situated on an inversion centre, is coordinated by four bridging Br atoms and two N atoms from two 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted octa-hedral geometry. The L ligand, which also lies across an inversion centre, bridges two Cd(II) ions, forming layers parallel to (010).

In the title coordination polymer, [CuBr(C(3)H(5)N(3)S)](n), the Cu(I) atom adopts a tetra-hdral CuS(2)Br(2) coordination geometry arising from two S-bonded 4-methyl-1H-1,2,4-triazole-3(4H)-thione ligands and two bromide ions. Both the S and Br atoms act as bridging ligands, connecting pairs of Cu(I) atoms and generating chains propagating in [100]. Inter-chain N-H⋯N hydrogen bonds generate lay...
