Catena-Poly[[[diaqua-(nitrato-κO,O')(2,2':6',2''-terpyridine-κN,N',N'')ytterbium(III)]-μ-cyanido-κN:C-[dicyanido-platinum(II)]-μ-cyanido-κC:N] acetonitrile monosolvate].

ABSTRACT: The title compound, {[PtYb(CN)(4)(NO(3))(C(15)H(11)N(3))(H(2)O)(2)]·CH(3)CN}(n), was isolated from solution as a one-dimensional coordination polymer. The Yb(3+) site has ninefold coordination with a distorted tricapped trigonal-prismatic geometry, while the Pt(II) ion is coordinated by four cyanide groups in an almost regular square-planar geometry. cis-Bridging by the tetra-cyanidoplatinate(II) anions links the Yb(3+) cations, forming chains. Additionally, each Yb(3+) is coordinated by two water mol-ecules, one bidentate nitrate anion, and one tridentate 2,2':6',2''-terpyridine mol-ecule. O-H⋯N hydrogen-bonding inter-actions are found between adjacent chains and help to consolidate the crystal packing. In addition, π-π stacking inter-actions exist between the terpyridine ligand and the t
