Increasing dimensionality [from 2D (1) to 3D (2)] and T(C) [from 10 (1) to 20 K (2)] in two new oxamato-bridged heterobimetallic Mn(II)(2)Cu(II)(3) open-frameworks result from the steric hindrance provided by the different alkyl substituents of the N-phenyloxamate bridging ligands. 相似文献

This paper reports a preliminary study of the nanospray ionisation mass spectrometry analyses of retinoic acid and retinal. The results are compared and contrasted to the results normally observed with electrospray ionisation. A significant difference in behaviour was observed for the balance between radical ion formation and protonated molecule formation for retinal. The results suggest that the influence of the very different ionisation conditions present in nanospray is very important in determining how ionisation is achieved and has potentially wide ranging applications in the fields of mass spectral analysis of biological and medical extracts. 相似文献
