Abstract

Bis(4-formyl-2-methoxyphenolato)bis(pyridine)copper(II) monohydrate crystallizes in the triclinic system:a = 10·432,b = 9·342,c = 13·799 Å, α = 103·75, β = 100·53, γ = 100·81 °,Z = 2, space groupP¯1.

The structure was determined by Fourier methods with Cukα diffractometer data, and refined by a combination of block-diagonal and full-matrix least squares toR = 0·068 for 2430 observed reflexions.

The copper atoms occupy the special positions 0, 0, 0 and 0,1/2, 1/2; hence, both molecules are centrosymmetric. Both the methoxy and phenolic oxygen atoms of the phenolate ions coordinate to the metal. These, together with coordinated nitrogen atoms from the pyridine molecules, give the copper atoms a six-fold coordination.

Hydrogen bonding between a water molecule and the phenolic oxygen atoms of adjacent molecules results in chains of molecules linked approximately along [011].
