摘 要: | 1 INTRODUCTION Supramolecular compounds assembled by coordination covalent bonding or hydrogen bonding are of considerable interest due to their potential applications in developing new materials with magnetic, optical and catalytic properties1]. One of the synthesis methods used to construct the functional compounds is that octahedral metal ion connects to polydentate ligand such as 4, 4?bipyridine, pyrazine and so on to form multi-dimensional supramolecular polymer2]. Hmt (hexamethyl…

Abstract: | The synthesis and crystal structure of Co(NCS)2(hmt)2(H2- O)2]穂Co(NCS)2(H2O)4]?H2O (hmt = hexamethylenetetramine) are reported. The crystal belongs to triclinic, space group P with unit cell parameters: a = 7.917(1), b = 9.023(1), c = 12.877(1) ? ?= 94.21(1), = 96.68(1), ?= 115.42(1)? C16H40Co2N12O8S4, Mr = 774.7, V = 817.33 3, Z = 1, Dc = 1.574 g/cm3, F(000) = 402 and (MoK? = 1.328mm-1. The final values of R and wR are 0.0251 and 0.0598, respectively, for 2545 observed reflections with I > 2(I). Each Co atom is in an octahedral coordination environment, and the independent uncharged components Co(NCS)2(hmt)2(H2O)2], Co(NCS)2(H2O)4] and H2O are linked together by three kinds of hydrogen bonds (O(2)H贩種(3) and O(3)H贩種(2), O(1)H贩稯(4) and O(3)H贩稯(4), O(2)H贩稴(2) and O(4)H贩稴(1)) to form a three-dimensional supramolecular architecture. |
