چکیده
The title compound, [Co(C(30)H(23)O(2)P(2))(C(3)H(9)P)(2)], was synthesized by the addition of a Co(PMe(3))(4) solution to (PPh(2)O)(2)C(6)H(4). The Co(I) atom displays a trigonal-bipyramidal geometry with the two P atoms of the 'PCP' pincer ligand and the P atom of one of the trimethyl phosphine ligands forming the basal plane, whereas the metalated C atom and the P atom of the second phospine ligand occupy the apical sites. The Co-C distance is 1.961 (2) Å and the C-Co-P angle is 171.96 (6)°.

The asymmetric unit of the title compound, [Co(2)(C(10)H(2)O(4)S(3))(2)(C(12)H(8)N(2))(4)]·2C(3)H(7)NO, contains one half of the formula unit, with the rest generated by inversion. The cobalt ion sits in a slightly distorted octa-hedral environment and is ligated to four N atoms of two 1,10-phenanthroline molecules and to two O atoms of two dithieno[3,2-b:2',3'-d]thio-phene-2,6-dicarb-oxy-l-ate...

The title complex, [Ni(4)(C(36)H(40)N(2)O(2))(2)(OH)(4)(C(3)H(9)OP)(2)(H(2)O)(4)]·2C(4)H(10)O·2C(3)H(9)OP·2H(2)O, is centrosymmetric with a central core that can be described as a defect double cubane. The four metal ions in the cluster are held together by four bridging hydroxide groups. Each Ni(II) atom adopts a distorted octa-hedral geometry.
