N,N-Dibenzyl-O,O′-dimethyl thiophosphate
The P atom in the title compound, C(16)H(20)NO(2)PS, is bonded in a distorted tetra-hedral P(S)(O)(2)N environment with the bond angles at the P atom in the range 99.37 (7) to 115.68 (5)°. The angles at the amido N atom (with bond-angle sum of 357.8°) confirm its sp(2) character. The C-O-P bond angles are 119.78 (11) and 119.39 (12)°.

In the title compound, [Co(C(7)H(5)O(3))(2)(C(14)H(12)N(2))], the Co(II) ion is five-coordinated by two N atoms from one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and three O atoms from two 2-hydroxy-benzoate anions in a distorted trigonal bipyramidal geometry. The carboxyl-ate group of one of the two 2-hydroxy-benzoate anions is monodentate with a normal Co-O distance [1.9804 (18) Å], w...

In the title compound, [Cd(C(8)H(7)O(3))(2)(C(14)H(12)N(2))], the Cd(II) ion is coordinated by two N atoms from a 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and four O atoms from two 2-meth-oxy-benzoate anions in a distorted octa-hedral environment. Two O atoms of one bidentate 2-meth-oxy-benzoate ligand are each disordered over two positions, with site-occupancy factors of 0.579 (4) and ...

The O-C(6)H(4)-CH=N-C(6)H(4)-O dianion of the title compound, [Mn(C(13)H(9)NO(2))(C(7)H(5)O(2))(C(2)H(6)OS)], acts as an O,N,O'-chelate to bind to the Mn(III) atom, and the three atoms constitute three points [O-Mn-O = 174.43 (11)°] of an octa-hedron around the metal atom. The azomethine linkage is disordered over two positions in a 0.657 (13):0.343 (13) ratio. The deprotonated salicyldehyde an...
