New mononuclear [Cu2(L1)2(H2O)]2H2O CH3OH] (cyCu)2, multinuclear [Cu2(L1)2K2][Ni(CN)4] (cyCuKNi), and dinuclear Ni(L1)Lu(NO3)3 (cyLuNi), Cu(L1)Lu(NO3)3 (cyLuCu) and Zn(L1)Lu[(NO3)2CH3COO]CH3OH (cyLuZn) complexes incorporating chiral Schiff base ligands were prepared and characterized by various techniques such as solid-state CD spectra, diffuse reflectance(More)
Preparations, crystal structures, and spectral and magnetic properties of two new chiral one-dimensional cyano-bridged coordination polymers, [Cu(II)L2]M(II)(CN)].2H2O (M(II) = Ni(II) (1) and Pt(II) (2), L = trans-cyclohexane-(1R,2R)-diamine) have been presented. Complex 1 crystallizes in the monoclinic P2(1) space group with a = 9.864(4) A, b = 15.393(8)(More)
Cocrystals of one-dimensional cyanide-bridged Cu-Cr or Cu-Co bimetallic assemblies and mononuclear Cu complexes, [Cu(chxn)2]3[M(CN)6]2·4H2O (chxn = trans-cyclohexane-(1R,2R)-diamine; M = Cr for 1 and Co for 2), and two-dimensional cyanide-bridged Cu-Fe bimetallic assembly, [Cu(N-Eten)2]3[Fe(CN)6]2·4H2O (N-Eten = Nethylethylenediamine) (3), were prepared and(More)
Photoinduced magnetization of the cyano-bridged 3d-4f heterobimetallic assembly Nd(DMF)4(H2O)3(mu-CN)Fe(CN)5.H2O (1) (DMF = N,N-dimethylformamide) is described in this paper. The chiMT values are enhanced by about 45% after UV light illumination in the temperature range of 5-50 K. We propose that UV light illumination induces a structural distortion in 1.(More)
Four chiral Schiff base binuclear 3d-4f complexes (NdNi, NdCu, GdNi, and GdCu) have been prepared and characterized by means of electronic and CD spectra, IR spectra, magnetic measurements, and X-ray crystallography (NdNi). A so-called artifact peak of solid state CD spectra, which was characteristic of oriented molecules without free molecular rotation,(More)
The title compounds, a hydrogen-bonded linear chain, [Mn(C18H18N2O4)(H2O)2]ClO4, (I), a hydrogen-bonded pseudo-dimer, [Mn(C16H10Cl4N2O2)(CH4O)(H2O)]ClO4, (II), and a dimer, [Mn2(C18H18N2O4)2(CH4O)2](ClO4)2, (III), respectively, have been structurally characterized. The three complexes are completely different in their structural features, despite identical(More)
This paper describes a microdroplet merging device that can actively control the merging of various droplets under a wide range of flow conditions, using a simple structure. The microdroplets were trapped and merged in a wide chamber divided by pillars, and their behavior was controlled by two horizontal pneumatic microactuators. Hydrodynamic flow control(More)
Three chiral Schiff base (bis(N-R-2-phenylpropyl-3,5-dichlorosalicydenaminato)) nickel(II), copper(II), and zinc(II) complexes have been investigated by means of electronic and CD (circular dichroism) spectra is the solid state as well as PMMA solutions of various concentration. Because these complexes possess long and flexible pendant groups, they are(More)
The title compound, [Cu(C(4)H(12)N(2))(2)(C(3)H(6)O)(2)](ClO(4))(2), is the first structurally characterized Cu(II) complex having acetone as axial ligands. The complex adopts an elongated octahedral trans-[CuN(4)O(2)] coordination geometry, with the Cu atom having 222 site symmetry. The axial Cu-O(acetone) and in-plane Cu-N bond lengths are 2.507 (5) and(More)
