Abstract:  Complex compound Ni(NCS)₂(pipe)₄ crystallizes in orthorhombic system with the space group С 222, and unit cell dimensions а = 76.08 pm, b = 194.96 pm, с = 176.03 pm, and Z = 4. The crystal structure was determined by heavy atom method and refined by least-squares method isotropically to R = 10.8%. The Ni(II) atom is pseudooctahedrally coordinated by two N atoms from the NCS groups with Ni—N distance 20.0 pm and by four N atoms from piperidine molecules with two different Ni—N distances: Ni—N(l) 22.8pm and Ni—N(2) 23.6 pm (two pairs of piperidine molecules in cis position). The NCS groups are bonded terminally through the nitrogen atoms.
