Abstract
The title complex, [Cu4(C5H12NO)2(C2H3O2)6(C4H8O)2]n, consists of dinuclear [Cu2(C5H12NO)2(THF)2] (THF is tetrahydrofuran) and [Cu2(CH3COO)4] units linked through acetate ions, generating parallel one-dimensional polymeric chains propagating in the [10] direction. In the first dinuclear unit, CuII ions related by inversion symmetry are bridged by two 3-(dimethylamino)propan-1-olate ligands. Likewise, a pair of inversion-related CuII ions are bridged by four acetate groups. The crystallographically independent Cu centers are linked to one another by a single bridging acetate group, generating an infinite chain. The distorted square-pyramidal coordination of the first metal center is completed with an apical THF molecule, with a long Cu—O bond length of 2.476 (5) Å. The geometry around the other metal atom is close to octahedral, and the Cu⋯Cu separation in this unit is 2.652 (1) Å. The distance between the metal centers in the first dinuclear unit is considerably longer [3.068 (1) Å], suggesting little or no bonding interaction. The Cu⋯Cu separation between two acetate-bridged independent Cu centers is 4.860 (2) Å. The THF molecule has methylene groups disordered over two positions, with occupancies of 0.608 (13) and 0.392 (13).

Tetranuclear complex 1 crystallizes in the monoclinic system, space group P2(1)/n, with unit cell parameters a = 8.284(8), b = 21.52(1), c = 11.432(3) A, beta = 105.19(2) degrees , Z = 2. Bi-dimensional complex 2 crystallizes in the triclinic system, space group P1, with unit cell parameters a = 8.184(5), b = 8.792(2), c = 10.887(2) A, alpha = 75.65(2), beta = 76.55(3), gamma = 74.36(3) degrees , Z = 2. Tetranuclear complex 3 crystallizes in the triclinic system, space group P1, with unit cell parameters a = 8.455(4), b = 9.114(9), c = 12.744(8) A, alpha = 104.62(8), beta = 99.86(6), gamma = 106.10(8) degrees, Z = 1. Dinuclear complex 4 crystallizes in the triclinic system, space group P1, with unit cell parameters a = 8.15(1), b = 8.18(2), c = 11.44(1) A, alpha = 69.39(2), beta = 80.36(2), gamma = 80.37(2) degrees , Z = 2. One-dimensional complex 5 crystallizes in the orthorhombic system, space group P2(1)2(1)2(1), with unit cell parameters a = 20.45(4), b = 11.36(3), c = 6.43(1) A, Z = 4. The magnetic behavior of all the complexes has been checked giving a bulk antiferromagnetic coupling in all the cases with |J| values in the range 109-144 cm(-1) for 1-4. Compound 5 is diamagnetic in the 2-300 K range of temperatures. The found J values 1-5 for can be justified from the structural data taking into account the orbital countercomplementarity for 1-4 and the orbital complementarity for 5.

Abstract
The phosphatidylcholine-preferring phospholipase C from Bacillus cereus (PC-PLC(Bc)) is a tri-Zn enzyme with two 'tight binding' and one 'loose binding' sites. The Zn2+ ions can be replaced with Co2+ and Cu2+ to afford metal-substituted derivatives. Two Cu2+-substituted derivatives are detected by means of 1H NMR spectroscopy, a 'transient' derivative and a 'stable' derivative. The detection of sharp hyperfine-shifted 1H NMR signals in the 'transient' derivative indicates the formation of a magnetically coupled di-Cu2+ center, which concludes that the Zn2+ ions in the dinuclear (Zn1 and Zn3) sites are more easily replaced by Cu2+ than that in the Zn2 site. This might possibly be the case for Co2+ binding. Complete replacement of the three Zn2+ ions can be achieved by extensive dialysis of the enzyme against excess Cu2+ to yield the final 'stable' derivative. This derivative has been determined to have five-coordinated His residues and an overall S'=1/2 spin state with NMR and EPR, consistent with the formation of a tri-Cu2+ center (i.e. a di-Cu2+/mono-Cu2+ center) in this enzyme. The binding of substrate to the inert tri-Cu2+ center to form an enzyme-substrate (ES) complex is clearly seen in the 1H NMR spectrum, which is not obtainable in the case of the native enzyme. The change in the spectral features indicates that the substrate binds directly to the trinuclear metal center. The studies reported here suggest that 1H NMR spectroscopy can be a valuable tool for the characterization of di- and multi-nuclear metalloproteins using the 'NMR friendly' magnetically coupled Cu2+ as a probe.

Abstract
A transition metal ion-templating reaction that has been widely exploited for the synthesis of nitrogen macrocycles, sepulchrates, and linear tetradentate ligands is the template-directed Mannich condensation of carbon acid and aldehyde equivalents with amines. In the course of investigating the copper(II) template-directed synthesis of linear tetradentate amino acid-containing ligands for the design and synthesis of double-strand DNA cleavage agents, we have trapped and characterized an intermediate in the templating reaction. Condensation of bis(phenylalaninato)copper(II) with formaldehyde and nitroethane led to a nitro-substituent-bearing precursor complex that upon reduction is crystallographically characterized as ((2S)-5-amino-2-benzyl-6-hydroxy-5-methyl-3-azahexanoate)copper(II) (space group P2(1)2(1)2(1), a = 9.0066(5) Å, b = 11.1040(6) Å, c = 16.009(2) Å, alpha = beta = gamma = 90.0 degrees, Z = 4, R(1) = 0.0265, wR(2) = 0.0612). NMR investigation of the precursor complex and the precursor and product ligands shows that the templated ligands each contain only a single phenylalanine unit, not the two phenylalanine units expected on the basis of similar synthetic procedures. The structure of the reduced product confirms this conclusion and provides structural characterization of a template intermediate trapped during ligand assembly.
