X-ray analyses of the structures of two crystalline forms of trans-dichlorotetrakis(ethylenethiourea)nickel(II)
摘要:
trans-Dichlorotetrakis(ethylenethiourea)nickel(II), Ni[SC(NHCH 2) 2] 4Cl 2, is polymorphous, crystallizing in the triclinic system with one molecule in the unit cell (space group P1) and in the monoclinic system with four molecules in the unit cell (space group C2/c). Both structures have the same NiS 4 skeleton, including two unequal independent Ni-S bonds, but differ in the orientation and length of the Ni-Cl bonds and also in the orientation of the ethylenethiourea ligands. There is no clear evidence for intermolecular or intramolecular hydrogen bonding in these crystals.
