چکیده
The Sn(IV) atom in the title compound, [Sn(C(4)H(9))(2)Cl(2)(C(12)H(8)N(2))], is chelated by the N-heterocycle; the n-butyl groups are trans to each other whereas the Cl atoms are cis to each other. The crystal studied was a non-merohedral twin with the minor domain being in a 15.8 (1)% proportion.

In the title compound, [Sn(CH(3))(2)(NSC)(2)(C(24)H(16)N(2))], a 1:1 adduct of dimethyl-tin diisothio-cyanate with 4,7-diphenyl-1,10-phenanthroline, the Sn(IV) atom shows a slightly distorted octa-hedral SnC(2)N(4) coordination. The methyl groups are trans to each other in the octa-hedron surrounding the metal atom [C-Sn-C = 176.61 (12)°].

In the asymmetric unit of the title compound, [Sn(C(4)H(9))(2)(NCS)(2)(C(12)H(8)N(2))], there are two independent mol-ecules, both lying on a twofold rotation axis. The axis passes through the mid-point of the 1,10 and 5,6 bonds of the N-heterocycle and through the Sn atom. The Sn atoms show a slightly distorted SnC(2)N(4) octa-hedral coordination.

In the title coordination polymer, [Cu(NCS)(2)(C(12)H(8)N(2))](n), the Cu(II) atom is situated on a twofold rotation axis and is coordinated by two N atoms from the bidentate 1,10-phenanthroline ligand and four thio-cyanate groups to confer a CuN(4)S(2) octa-hedral geometry and resulting in a layer structure extending parallel to (100).

The title complex, [Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)](n), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand...
